Summary: This study investigates the impact of highly dispersed metal oxides of Co-Cu, Cu-Fe, and Co-Fe m-FTS systems on the direct synthesis of higher alcohols (HA) and demonstrates the viability of ZrO2 as a promoter. The addition of ZrO2 significantly increases HA productivity, with the Cu(1)Co(4)@ZrO2-5 catalyst exhibiting a 2.5-fold increase compared to its ZrO2-free counterpart. The Co1Fe4@ZrO2-10 catalyst shows the most productive performance among similar systems.

Summary: This study successfully created a method to use Cu for removing NOx on alpha-Fe2O3, which showed excellent low-temperature performance, high selectivity, and strong water and sulfur resistance. The presence of Cu2+ ions in the crystal lattice of Fe2O3 formed a solid solution and changed its property. This adjustment of Cu2+ ions increased Lewis acid sites and lattice defects, which facilitated the generation and adsorption of NO2, nitrate, and nitrite species, leading to high NH3-SCR activity. The regulation of Cu also strengthened the redox ability and oxygen vacancy, crucial for the fast SCR reaction. The results provided inspiration for the development of green and efficient catalysts for NOx removal in practical industrial applications.

Summary: A series of catalysts prepared by thermal decomposing CoMn-MOF materials were used for the synthesis of higher alcohols (HA) from syngas. The catalyst with a remaining MOF framework exhibited excellent stability and displayed a superior selectivity to HA, with an alcohol selectivity of 57.5% and a distribution of C2+OH in total alcohols up to 82.4% at a CO conversion of 51.5%. This study highlights a feasible strategy for designing highly efficient catalysts for HA synthesis via partial decomposing MOF materials.

Summary: In this study, a photo-assisted thermal catalytic Fischer-Tropsch reaction over bimetallic Co-Cu/CeO2 was investigated. It was observed that alcohols could be produced under 3 MPa at 180 degrees C in the absence of light. With light irradiation, the yield of alcohol increased by 1.5 times while maintaining the selectivity at the same temperature. The research suggested that Co acted as the active site for CO adsorption and catalyzed hydrogenation reactions to produce alcohols. Under irradiation, CeO2 generated photo-generated electrons that were transferred to Co, enhancing the electron-rich density and facilitating the adsorption and activation of CO. Furthermore, the light induced Cu to produce localized surface plasmon resonance (LSPR) and excite hot electrons, promoting the dissociation of H-2 and the regeneration of oxygen vacancies on the CeO2 surface. Both light-induced behaviors contributed to the enhancement of the Fischer-Tropsch reaction.

Summary: Ordered mesoporous Cu-La-Al composite metal oxides were synthesized via an evaporation induced self-assembly method and exhibited excellent catalytic activity, selectivity, and stability in upgrading ethanol to higher alcohols. The superior performance was attributed to the presence of octahedrally coordinated Cu2+ and acid-base sites on the catalyst surface, as well as the highly stable CuAl2O4 active phase.

Summary: This work investigates the catalytic mechanism of a bifunctional catalyst composed of Cu-modified Fe-based catalyst and ZSM-S in selective CO2 hydrogenation to aromatics using XRD, H-2-TPR, CO2-TPD, SEM, TEM, and N-2 adsorption and desorption techniques. The results show that the Cu promoter improves carbon chain growth, suppresses methane formation, and enhances aromatic selectivity. By lengthening the straight channel length of zeolites in the direction of the b-axis, a STYtoulence of 14.8 g(CH2).kg(cat)(-1).h(-1) is achieved. This study provides insights for designing a bifunctional catalyst with high productivity of high value-added aromatics.

Summary: The aim of this study was to investigate the role of mesoporous silica-carbon composite (SCn) materials as a support for iron based FT catalyst. SCn material with high surface area, ordered mesoporosity and narrow pore size distributions facilitated the diffusion of reactant gas molecules and acted as nanoreactors for the conversion of syngas to liquid hydrocarbon. The addition of copper and carbon promoted the reduction of iron species and the growth of active metal species, while suppressing the formation of silica-iron complexes. This study has significant implications for the development of iron based catalysts for pilot scale investigation of FT reaction.

Summary: In this study, a CoMnOx nanocomposite catalyst prepared by the sol-gel method was found to selectively produce short-chain alcohols, particularly ethanol, in higher alcohol synthesis from syngas. The presence of oxygen vacancies in MnOx was shown to enhance the reaction and interact with neighboring Co2C, leading to the production of ethanol and other short-chain alcohols in HAS.

Summary: This work investigates the influence of carbon source and molar ratio in the Fe-Ti-C system on the size, distribution, and morphology of TiC particles in TiC/Fe composites. The results show that the size of TiC particles decreases with increasing Fe content, and the shape changes from spherical to cubic. Different carbon sources and molar ratios also lead to variations in the mechanical properties of the composites.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
