Abstract
Official abstract text for this publication.
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-Mo 2 C/γ-Al 2 O 3 , A=K, Na, Li). The A-Mo 2 C/γ-Al 2 O 3 catalyst is synthesized by co-impregnation of molybdemun and alkali metal precursors onto a γ-Al 2 O 3 support. It is then carburized to form the A-Mo 2 C/γ-Al 2 O 3 .
First claim
Opening claim text (preview).
What is claimed as new and desired to be protected by Letters Patent of the United States is: 1. A supported heterogeneous catalyst material for catalyzing the reverse water-gas shift (RWGS) reaction for the selective formation of CO, comprising: a support material comprising γ-Al 2 O 3 ; and an active material comprising alkali-metal doped molybdenum carbide, wherein the alkali-metal component of the active material comprises one or more alkali-metal precursors in elemental form or in the form of oxides, said metal being Na. 2. A supported heterogeneous catalyst material for catalyzing the reverse water-gas shift (RWGS) reaction for the selective formation of CO, comprising: a support material comprising γ-Al 2 O 3 ; and an active material comprising alkali-metal doped molybdenum carbide, wherein the alkali-metal component of the active material comprises one or more alkali-metal precursors in elemental form or in the form of oxides, said metal being Li.
