Abstract
A supported heterogeneous catalyst material for catalyzing the reverse water-gas shift (RWGS) reaction for the selective formation of CO using an alkali metal-doped molybdenum carbide on a gamma alumina support (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.
