Abstract
A molybdenum carbide compound is formed by reacting a molybdate with a mixture of hydrogen and carbon monoxide. By heating the molybdate powder from a temperature below 300° C. to maximum temperature 850° C., a controlled reaction can be conducted wherein molybdenum carbide is formed. A high surface area, nanograin, metastable molybdenum carbide can be formed when the reaction temperature is below 750° C. The metastable molybdenum carbide is particularly suitable for use as a catalyst for the methane dry reforming reaction.
Claims7
A method of forming a Mo2Cy compound wherein y is 0.95 to 1.05 comprising heating a molybdate to a temperature of 300° C. and then from 300° C. to less than 850° C. at a ramp rate of 2 to 20° C./min in a gaseous blend of a reducing gas and a carburizing gas for a time effective to convert said molybdate to Mo2Cy.
