Molybdenum Carbide as Alternative Catalysts to Precious Metals for Highly Selective Reduction of CO2to CO

Abstract Rising atmospheric CO 2 is expected to have negative effects on the global environment from its role in climate change and ocean acidification. Utilizing CO 2 as a feedstock to make valuable chemicals is potentially more desirable than sequestration. A substantial reduction of CO 2 levels requires a large‐scale CO 2 catalytic conversion process, which in turn requires the discovery of low‐cost catalysts. Results from the current study demonstrate the feasibility of using the non‐precious metal material molybdenum carbide (Mo 2 C) as an active and selective catalyst for CO 2 conversion by H 2 .
