摘要

Co-MOF-74 materials were synthesized at different temperatures using solvothermal method. The effect of the synthetic temperature on the structure and low temperature NH3-SCR catalytic performance of Co-MOF-74 was systematically investigated. Co-MOF-74 synthesized at 100 degrees C has flower-like morphology, while hexagonal prism structures could be obtained at other temperatures. Co-MOF-74 with flower-like morphology has a larger specific surface area and pore volume compared with the hexagonal prism ones. The highest catalytic activity was obtained at 200 degrees C under the optimal synthesis temperature, which was attributed to the combination of special morphology, the highest specific surface area and Co content.

Insight into the praseodymium effect on the NH3-SCR reaction pathways over W or Nb supported ceria-zirconia based catalysts

Charlotte Croise, Remy Pointecouteau, Joudia Akil, Alain Demourgues, Nicolas Bion, Xavier Courtois, Fabien Can

Summary: The study found that partial substitution of zirconium for praseodymium in a ceria-zirconia support can enhance the support reducibility, but impregnation of niobium and tungsten inhibits the redox behaviors. Additionally, niobium and tungsten provide acidic sites while praseodymium inhibits ammonia storage and decreases deNO(x) performances. The various redox and acidic behaviors observed in the studied materials demonstrate a strong competition between NOx SCR and NH3 oxidation pathways.

A new type bimetallic NiMn-MOF-74 as an efficient low-temperatures catalyst for selective catalytic reduction of NO by CO

Yong Shi, Qi Chu, Wei Xiong, Jinsuo Gao, Lei Huang, Yaqi Zhang, Yue Ding

Summary: A series of Ni-Mn mixed bimetal-organic frameworks catalysts were synthesized using solvothermal method, showing significant improvement in catalytic performance compared to monometallic Ni or Mn-MOF-74. Especially, Ni0.65Mn0.35-MOF-74 catalyst achieved nearly 100% NO conversion at 175 degrees C with nearly 100% N-2 selectivity at 200 degrees C. The synergistic effect between Ni and Mn species was found beneficial for the formation of more active Mn4+ and Ni3+ components and Lewis acid sites for NO elimination.

Highly reactive methyl group drives selective catalytic reduction of NOx by methanol on bismuth oxide nanoparticle implanted FER zeolite

Han Sun, Fei Han, Lu Sun, Shinya Mine, Takashi Toyao, Yunpeng Liu, Zhonghua Wu, Masaaki Kitano, Masaya Matsuoka, Weiwei Liu, Yongqiang Dai, Meiqing Shen, Haijun Chen

Summary: Selective catalytic reduction by methanol (Methanol-SCR) is a promising technology for treating exhaust with high concentration of sulfur. A new catalyst of nano-bismuth oxide implanted FER zeolites (Bi-FER) has been successfully synthesized, showing a lower optimum reaction temperature compared to existing technology. The reactivity of methyl groups generated on Brønsted acid sites neighboring with nano-bismuth oxide has been found to be highly effective for NOx removal. Therefore, a strategy of methanol activation to produce reactive methyl groups has been proposed for improving Methanol-SCR catalysts.

Variations in the physicochemical properties of spent honeycomb V2O5-WO3/TiO2 catalysts from PC and CFB boilers SCR denitration systems

Chaolu Wen, Yanxia Guo, Kezhou Yan, Huirong Zhang

Summary: The production of spent honeycomb V2O5-WO3/TiO2 catalysts has caused serious environmental hazards. This study focused on the changes of typically spent catalysts from pulverized coal (PC) and circulating fluidized bed (CFB) boiler deNOx systems, including morphologies, pore structure, chemical composition, carrier, and active components properties. The major deactivation factors were pore blockage caused by fly ash and sulfur deposition, with CFB catalysts being more easily deactivated due to severe pore structure loss. The transformation of anatase to rutile TiO2 and the shift in valence state of V were major contributors to irreversible deactivation. This research provides valuable insights into the deactivation mechanism and potential recycling of spent catalysts.

Palladium supported on mixed-metal-organic framework (Co-Mn-MOF-74) for efficient catalytic oxidation of CO

Reda S. Salama, Mohammed A. Mannaa, Hatem M. Altass, Amr Awad Ibrahim, Abd El-Rahman S. Khder

Summary: Successful synthesis of monometallic and bimetallic metal-organic frameworks with different Co/Mn ratios under solvothermal conditions, followed by deposition of Pd nanoparticles. Characterization results show that Pd nanoparticles were finely dispersed on the MOFs surfaces. The catalytic activity of monometallic MOFs was enhanced by introducing another metal in the same framework, while loading with Pd nanoparticles showed an excellent improvement in CO conversion. Samples containing Pd nanoparticles exhibited higher catalytic activities with increasing Pd content.

Synthesis of Bimetallic Ag-Ni-MOF-74 Catalyst with Excellent CO-SCR Performance in Low Temperature Range

Yaqi Zhang, Qi Chu, Yong Shi, Jinsuo Gao, Wei Xiong, Lei Huang, Yue Ding

Summary: A series of bimetal organic-frameworks catalysts with different Ag contents were successfully prepared by a post-synthesis method and evaluated for NO reduction by CO. The bimetallic Ag-Ni-MOF-74 catalysts exhibited a better low-temperature CO-SCR efficiency than monometallic Ni-MOF-74 catalysts, with Ag1-Ni-MOF-74 achieving nearly 100% NO conversion in the temperature range from 200 degrees C to 300 degrees C. The addition of Ag enriched the form of active sites, increased the specific surface area of the catalysts, promoted the activation and transfer of reactants, and the synergistic effect between Ag and Ni species enhanced surface oxygen vacancies and accelerated electron transfer in the NO+CO reaction. The mechanism of CO-SCR reaction over Ag-Ni-MOF-74 was proposed to follow Langmuir-Hinshelwood (L-H) mechanism, exhibiting a more readily low-temperature reaction rate and a lower reaction barrier than Eley-Rideal (E-R) mechanism.

NiMn mixed oxides with enhanced low-temperature deNOx performance: Insight into the coordinated decoration of MnOx by NiO phase via glycine combustion method

Xu Wu, Lili Liu, Jiangning Liu, Benhui Hou, Yali Du, Xianmei Xie

Summary: A series of Ni and Mn based single/double metal oxides were prepared using a facile glycine combustion method and tested for low temperature selective catalytic reduction of NO with NH3. The NiMn-400 sample exhibited outstanding catalytic performance with high NOx conversion, N2 selectivity, and SO2 resistance. The enhanced activity of NiMn-400 catalyst could be attributed to the coordination of Ni and Mn, higher Mn4+/Mnn+ ratio, suitable acid sites, and redox capacity.

(FeMnCe)-co-doped MOF-74 with significantly improved performance for overall water splitting

Ning Chai, Yuxuan Kong, Tian Liu, Shuanglu Ying, Qiao Jiang, Fei-Yan Yi

Summary: Developing inexpensive and efficient non-precious metal electrocatalysts for water splitting reactions is crucial. In this study, a series of 3d-4f (FeMnCe)-trimetallic MOF-74 with different ratios of metal centers were designed. FeMn6Ce0.5-MOF-74/NF exhibited excellent electrocatalytic properties for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in an alkaline solution. Moreover, the overall water splitting system using FeMn6Ce0.5-MOF-74/NF as the anode and cathode only required a voltage of 1.65 V to achieve a current density of 10 mA cm(-2).

Analogous Mechanistic Features of NH3-SCR over Vanadium Oxide and Copper Zeolite Catalysts

Hiroe Kubota, Takashi Toyao, Zen Maeno, Yusuke Inomata, Toru Murayama, Naoto Nakazawa, Satoshi Inagaki, Yoshihiro Kubota, Ken-ichi Shimizu

Summary: In this study, the researchers investigated the reduction/oxidation half-cycles of the selective catalytic reduction of NO with NH3 at 200 degrees C using in situ and operando spectroscopies. They proposed a general mechanism that is applicable to both V and Cu catalysts, where N-2 and H2O are formed during the reduction half-cycle and the regenerated V(V) or Cu(II) sites react with surface H+ to produce H2O during the oxidation half-cycle. The results provide comprehensive evidence of the general mechanism of NH3-SCR.

Selective catalytic reduction of NOx with NH3 over a novel MOF- derived MnOx catalyst

Ruiyang Chen, Xiaoyu Fang, Zhenguo Li, Zhiming Liu

Summary: In this study, a novel MnOx catalyst derived from MOF was fabricated and showed excellent activity and SO2 tolerance for the selective catalytic reduction of NOx by NH3 at low temperatures. The addition of MOF precursor and doping PVP improved the catalyst's surface area, particle size, and crystalline defects. The Mn-MP catalyst exhibited abundant acid sites, Mn4+, and surface chemical oxygen, which promoted the NH3-SCR reaction. In situ DRIFTs revealed that the high SO2 tolerance of the catalyst was attributed to the reduced irreversible sulfurization rate and the promoting adsorption of active bidentate nitrates and NH4+ in the presence of sulfates.

Plant breeding systems influence the seasonal dynamics of plant-pollinator networks in a subtropical forest

Minhua Zhang, Fangliang He

Summary: The study found that in a subtropical monsoon forest in China, there were no significant seasonal differences in network specialization, nestedness, and modularity of plant-pollinator interactions between the rainy season and dry season. However, there were significant differences in plant community robustness and pollinator specialization between seasons, especially when considering dioecious plants. Additionally, a trade-off variation in flower abundance between dioecious and hermaphroditic plants was observed between the rainy and dry seasons.

Geographic variation in the robustness of pollination networks is mediated by modularity

Hanlun Liu, Zheyi Liu, Minhua Zhang, Jordi Bascompte, Fangliang He, Chengjin Chu

Summary: The study reveals that the geographic variation of network robustness is mediated by modularity, with phylogenetic diversity showing a latitudinal trend towards the tropics on mainlands but towards the poles on islands under specialist-first removals. Modularity promotes robustness, while insularity and precipitation seasonality directly dampen it. Additionally, actual evapotranspiration and precipitation seasonality indirectly increase robustness through the mediation of modularity, while the interaction between precipitation seasonality and insularity decreases it.

Summary: The study found that arbuscular mycorrhizal (AM) trees predominantly contribute to decreasing total beta-diversity, reducing turnover, and increasing nestedness with increasing latitude, while the wide distributions of ectomycorrhizal (EcM) trees do not generate strong compositional differences among localities. Environmental variables, especially temperature and precipitation, are strongly correlated with beta-diversity patterns for AM trees and all trees, rather than for EcM trees.

Effects of the Climatic Region on Richness Correlations between Vascular Plants and Vertebrates in Nature Reserves of China

Sha Jiang, Fanhua Kong, Rui Hu, Jiaxin Zhang, Minhua Zhang

Summary: This study investigates the richness correlations among taxonomic groups and the underlying ecological mechanisms in subtropical and temperate regions of China. The results suggest that climate region affects the correlations in species richness, and the effectiveness of vascular plants as indicator taxa varies with climate region and target taxa. Energy and habitat heterogeneity are ecological drivers of richness correlations among taxonomic groups. The findings provide new evidence for understanding the variation and underlying mechanisms of richness correlations and highlight the importance of climatic variables and habitat heterogeneity in determining correlations between vascular plants and vertebrates.

Pioneer tree species accumulate higher neighbourhood diversity than late-successional species in a subtropical forest

Fanhua Kong, Xiaorong Chen, Minhua Zhang, Yu Liu, Sha Jiang, Ryan A. Chisholm, Fangliang He

Summary: A long-standing paradigm in ecology states that species diversity in a community increases over succession. However, there is limited understanding of the accumulation of neighbourhood diversity and its contribution to community diversity. In this study, we investigated the neighbourhood diversity of different functional groups of trees in a forest plot in subtropical China. We found that early successional species played a crucial role in accumulating neighbourhood diversity and contributing to overall plant community diversity. These results highlight the importance of conserving secondary forests, which are predominantly composed of early successional species.
