Figure Abstract

Caption

Researchers engineered a Ni/Mo2CTx MXene catalyst that undergoes transformation during the CO2 thermocatalytic hydrogenation, reducing the Ni particle size from 12.9 to 3.1 nm and increasing CO selectivity from 21.1% to 92.6% while maintaining CO2 conversion. This change stems from strong Ni-Mo interactions that enhance electron transfer. Mechanistic studies indicate that this dynamic structural evolution suppresses the formate pathway and leads to a product selectivity shift from methane to CO, providing a strategy for creating robust and selective MXene-based catalysts.
