Summary: Core@shell Ni@Co and bimetallic alloyed Ni-Co nanoparticles with controlled Co/Ni compositions were supported on CeO2 for catalytic dry reforming of methane (DRM). Increasing the Co/Ni ratio reduced coke deposition while maintaining catalytic activity. However, a Co/Ni ratio > 1 caused a rapid decrease in activity.

Summary: Sandwich structured core-shell Ni-Phyllosilicate@Ce1-xZrxO2 catalysts with optimal Zr loading in the Ce1-xZrxO2 shell are found to greatly enhance the intrinsic activity for DRM due to increased lattice oxygen mobility of the ceria-zirconia shell and stronger metal-support interaction with Ni. Involvement of lattice oxygen in methane activation and dissociation contributes to the higher DRM activity of the Zr-doped catalyst with maximum oxygen storage capacity, as inferred from rigorous kinetic and mechanism studies.

Summary: Ni-CeZrAl catalyst prepared by co-precipitation method demonstrated high performance in dry reforming of methane, with the highest methane conversion reaching 38.1%. The superior catalytic behavior was attributed to the high dispersion of surface Ni-0 active phase, abundant oxygen vacancies, and basic sites. In contrast, Ni-CeAl and Ni-CeZr showed inferior catalytic performance due to weak interaction and fewer active sites.

Summary: Pressurized dry reforming of methane (DRM) is highly desirable for its economic and efficient benefits, but the risk of catalyst carbon deposition is a concern. This study explored the use of hydrotalcite-derived Ni-Ir/MgAl(O) catalysts with different Ir/Ni molar fractions to enhance stability and carbon tolerance in pressurized DRM reactions. The addition of Ir was found to improve catalyst performance and inhibit carbon deposition, leading to improved durability and resistance to coke formation in high pressure DRM processes.

Summary: Dry reforming of methane is an efficient way to utilize carbon dioxide. This study utilized mesoporous silica support SBA-15 and microporous silica support beta as catalyst supports, and obtained highly dispersed Ni nanoparticles on Ni-SBA-15 and Ni-beta catalysts prepared by ammonia evaporation method. The Ni-SBA-15 and Ni-beta catalysts showed excellent catalytic activity, with a CO2 conversion of ca. 89 % and a CH4 conversion of ca. 84 % at 700 degrees C and nearly 100 % conversions at 800 degrees C. The mesopores of SBA-15 provided confinement for Ni nanoparticles, preventing Ni sintering and carbon deposition. However, the smaller pore size of beta hindered the introduction of Ni into its micropores, leading to more intensive Ni sintering and carbon deposition.

Summary: Ni and Ni-Mg phyllosilicate mesoporous SBA-15 catalysts prepared via ammonia evaporation (AE) method exhibit superior catalytic performance in CO2 methanation compared to catalysts prepared via wetness impregnation (WI) method, due to enhanced metal-support interaction and weakly basic sites provided by surface hydroxyl groups. Incorporation of Mg into phyllosilicate structure increases medium basic sites, promoting monodentate formate formation and improving CO2 methanation activity. Additionally, the turnover frequency of CO2 conversion is correlated with the concentration of basic sites, and the strong metal-support interaction and confinement effect of SBA-15 can suppress metal sintering, ensuring good stability.

Summary: In this study, it was demonstrated through experiments and theoretical calculations that the A-site lanthanide in perovskite-type oxygen carriers plays a crucial role in controlling the Fe-O covalency and hence the syngas yield. A smaller A-site cation radius was found to induce severe geometric tilting of the FeO6 octahedra, weakening the Fe-O orbital hybridization and reducing the oxygen mobility and surface oxygen activity. The charge-transfer energy was identified as a useful tool for designing oxygen carriers rationally and enhancing the understanding of oxygen modulation in chemical looping technologies.
