High-Performance Bimetallic Catalysts for Low-Temperature Carbon Dioxide Reforming of Methane

Catalytic dry reforming of methane (DRM) is a promising way for renewable syngas production due to the utilization of both CO2 and CH4 greenhouse gases. Current approaches were made to improve the catalytic activity and coke resistance by introducing a second metal into the Ni-based catalytic system. This bimetallic catalytic system showed a significant improvement in coke resistance due to the synergistic effect of both metals towards the reaction. This review summarizes recent developments in bimetallic catalysts in DRM which focused on the evaluation of catalysts, deactivation studies, and reaction mechanisms of developed bimetallic catalysts.
