Defect-Driven Efficient Selective CO₂ Hydrogenation with Mo-Based Clusters.

ABSTRACT: Synthetic fuels produced from CO₂ show promise in combating climate change. The reverse water gas shift (RWGS) reaction is the key to opening the CO₂ molecule, and CO serves as a versatile intermediate for creating various hydrocarbons. Mo-based catalysts are of great interest for RWGS reactions featured for their stability and strong metal-oxygen interactions. Our study identified Mo defects as the intrinsic origin of the high activity of cluster Mo₂C for CO₂-selective hydrogenation. Specifically, we found that defected Mo₂C clusters supported on nitrogen-doped graphene exhibited exceptional catalytic performance, attaining a reaction rate of 6.3 g_CO/g_cat/h at 400 °C with over 99% CO selectivity and good stabilit
