Summary: This study achieved plasma-catalytic dry reforming of biogas using Ni-based bimetallic catalysts, which resulted in high conversion, yield and selectivity of key gas products, and high fuel production efficiency (FPE). The coupling of DBD with 10Ni3Co showed the best reaction performance, and also helped suppress carbon deposition and reduce energy costs. The use of Ni-based catalysts allowed for tuning of product distribution, favoring the generation of C3-C4 hydrocarbons and syngas. The 10Ni3Co catalyst exhibited superior performance due to factors such as higher specific surface area, improved CO2 adsorption capability, strong metal-support interactions, enhanced reducibility, and Ni-Co alloy formation.

Summary: In this study, Ni-Cu alloy nanoparticles encapsulated in SiO2 nanospheres were used for CO2 reforming with methane (CRM) reaction. The combination of alloy effect, size effect, metal-support interaction, and confinement effect exhibited high performance, good sintering resistance, and trace carbon deposition in CRM. The appropriate Cu-addition catalysts showed better performance than the excessive Cu-addition catalysts, and the synergy of various effects in the 0.5CuNi@SiO2 catalyst contributed to the highest rates of CH4 and CO2 conversion in CRM reported so far.
