Abstract

A method for CO2 hydrogenation via the reverse water-gas shift (RWGS) reaction using alkali metal-doped molybdenum carbide, supported on gamma alumina (A-Mo2C/γ-Al2O3, A=K, Na, Li). The A-Mo2C/γ-Al2O3 catalyst is synthesized by co-impregnation of molybdemun and alkali metal precursors onto a γ-Al2O3 support. It is then carburized to form the A-Mo2C/γ-Al2O3. Also disclosed is the related catalyst material.
