Summary: A series of indium-modified manganese oxide catalysts were prepared and studied for their catalytic properties. The appropriate amount of indium modification was found to greatly enhance the activity, surface area, and acid site strength of the catalysts. The Mn-InO-6 catalyst exhibited the best performance, achieving nearly 100% NOx conversion in a certain temperature range. In addition, the indium doping improved the sulfur resistance of the catalysts. In situ DRIFT experiments revealed the mechanisms of the NH3-SCR reaction over Mn-InO-6 catalysts.

Summary: In this study, we enhanced the catalytic activity and SO2 tolerance of MnCeOx catalyst by modifying it with Nb5+ and Fe3+ co-doping. This improvement was achieved by optimizing the surface acidity, surface adsorbed oxygen, and electronic interaction of the catalyst. The NbFeMnCeOx catalyst exhibited excellent resistance to SO2, with less SO2 being adsorbed and easier decomposition of ammonium bisulfate (ABS) formed on its surface, as well as fewer sulfate species formed. Additionally, we proposed a possible mechanism for how Nb5+ and Fe3+ co-doping enhances the SO2 poisoning resistance of MnCeOx catalyst.

Summary: This article proposes an effective strategy to fabricate a series of catalysts by loading MnOx onto TiOx nanorod arrays, showing promising low-temperature denitration efficiency in the temperature range of 100-300 degrees C. The TiOx nanorod arrays provide a high surface area to load the active sites and improve the interaction between Ti and Mn elements, leading to apparent advantages on the content of surface chemical oxygen for promoting the fast SCR reaction in comparison with Mn-Ti catalysts prepared with a similar approach.

Summary: MnOx catalysts with 3D structure (Mn-HT) were prepared using KIT-6 as a template by the hard-template method, and their catalytic performance for the selective catalytic reduction of NOx by NH3 was investigated at low temperatures. It was found that the template KIT-6 prepared at different hydrothermal temperatures significantly affected the catalytic performance of Mn-HT catalysts. Among them, Mn-140 catalyst prepared using the template obtained at a hydrothermal temperature of 140 degrees C exhibited the highest catalytic performance. Characterizations showed that Mn-140 catalyst possessed high reducibility with abundant surface oxygen species and Mn4+ species. NH3-TPD and in situ DRIFTS demonstrated that there were more Lewis acid sites and Bronsted acid sites on the surface of Mn-140 catalyst, promoting the adsorption and activation of NH3 and efficiently reducing NOx mainly by the Eley-Rideal (E-R) mechanism, accompanied by the Langmuir-Hinshelwood (L-H) mechanism.

Summary: The study found that Mn doping can significantly improve the low-temperature denitrification activity of nitrided cotton straw biochar. Mn doping increases the NH3 adsorption capacity of the catalyst by introducing Bronsted and Lewis acid sites on its surface. The Mn doping also produces monodentate nitrite which can be reduced by NH3 at low temperatures, leading to enhanced low-temperature denitrification activity of the catalyst.

Summary: This study investigates the impact of metal doping on the DeNOx and anti-poisoning performance of MnOx/mZrO2. The results show that Sm doping has a more significant effect on both the DeNOx performance and anti-poisoning performance, while Co doping has a relatively minor impact on the DeNOx performance. This is because the interaction between Sm and Mn results in improved redox performance and the presence of more acidic sites, inhibiting the formation of sulfate and ammonium sulfate.

Summary: The study investigates the mechanisms of carbon monoxide (CO) oxidation on two SCR catalyst models and finds that the CO oxidation cycle consists of two key stages. The activation energy for CO oxidation on V2O5/TiO2 surface is lower than that on V2O5-WO3/TiO2, indicating that WO3 doping inhibits the CO oxidation.

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.

Summary: The simultaneous addition of NOx and NH3 has a significant impact on the oxidation of toluene over the MnOx-CeO2 catalyst, with NH3-SCR reactants and NO2 adsorption state playing important roles in deactivation. Adsorbed NO2 can enhance toluene oxidation, while nitrate species on the surface are inactive. NO2 adsorption is the weakest among the reactants, limiting its promotion of toluene oxidation.

Summary: Different crystal phases of MnO2 were synthesized and tested for NH3-SCR of NO and NH3 oxidation performances, showing varying reactivities towards oxygen and NH3 species on the catalyst surfaces. Alpha-MnO2 exhibited superior SCR performance for NOx conversion, while beta-MnO2 showed lower reactivity for N2O production due to NH3 adsorbed at Lewis sites. Gamma-MnO2 yielded similar NOx conversion rates as alpha-MnO2 but produced more N2O from SCR reactions. Delta-MnO2 mainly generated N2O from SCR reactions and had difficulty reacting with O-2.

Summary: The self-assembly of lanthanide ions with ditopic organic spacers leads to complex tiling patterns mimicking the structural motifs of quasi-periodic 2D materials. The linking of trans-{LnI(2)}(+) nodes by 4,4'-bipyridine results in rare examples of Archimedean tessellations in metal-organic frameworks, demonstrating significant magnetic exchange interactions and slow relaxation of magnetization behavior. The implementation of Archimedean tessellations in lanthanide(III) coordination solids provides a strategy to design elusive quasi-periodic metal-organic frameworks with inimitable magnetic properties.

Summary: This study investigates the chemisorption and reactions of nitric oxide (NO) on crystals of complexes containing dicobalt sites. The results show that a cascade of reactions occurs inside the crystals, resulting in the synthesis of nitrite and other gaseous NOx. The structural elucidation of the synthesized compound was achieved through recrystallization. The study suggests that these selective chemisorptive substrate reactions in the solid-state have significant implications for solvent-free chemical synthesis.

Summary: H-2-temperature-programmed reduction (TPR) and electronic paramagnetic resonance (EPR) spectroscopy were used to quantify two families of Cu-species in dehydrated Cu-CHA zeolites. Proper quantification of the Z(2)Cu sites required simulation of the EPR spectra and analysis of the Gaussian fit of the H-2-TPR data. The study revealed differences in the distribution and reducibility of the Cu species within the Z(2)Cu sites in this particular CHA zeolite.

Summary: We reported a photo-induced dehydrogenative N-N coupling of diarylimines, diarylamines, carbazoles, and anilines. This homo-coupling reaction only requires the combination of di-tert-butyl peroxide (DTBP) and light irradition. The protocol is simple, catalyst- and metal-free, and has a good substrate scope. Preliminary mechanistic studies suggest that the reaction proceeds via photo-induced homolytic cleavage of the peroxide followed by hydrogen atom transfer leading to the formation of N-centered radicals.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development.
