Stable and selective syngas production from dry CH4-CO2 streams over supported bimetallic transition metal catalysts

Syngas production from CH4 and CO2 was investigated over bimetallic nickel-cobalt catalysts, promoted by a CeZrO2 redox component. The appropriate design of active sites responsible for methane and CO2 activation (bimetallic clusters below 45 nm, adjacent to oxygen vacancy sites of the CeZrO2 solid solution) enabled kinetic balancing of both reaction halves, producing catalysts that are highly resistant to carbon accumulation in a wide range of...
