Mechanochemical synthesis of highly dispersed Cu on CeO2 for the reverse water-gas shift reaction

Copper-based catalysts are highly promising for carbon dioxide (CO2) reduction to carbon monoxide (CO) via the reverse water-gas shift (RWGS) reaction, owing to their efficiency, copper abundance, sustainability and cost-effectiveness. However, enhancing CO2 conversion and CO selectivity requires ac...
