    摘要: Anode catalysts for conversion of hydrocarbon feeds in solid oxide fuel cell membrane reactors. An anode catalyst may be a mixture of a metal with a metal oxide, for example a mixture of copper or copper-nickel alloy or copper-cobalt alloy with Cr2O3. Mixed oxides can be prepared by dissolving into water soluble salts of the different metals, chelating the metal ions with a chelating agent, neutralizing the solution, removing water by evaporation to form a gel which then is dried, and finally heating the dried gel to form a mixed oxide of the different metals. The chelating agent can be citrate ions, and ammonia can be added to the solution until the pH of the solution is about 8. The mixed oxide so formed then is reduced, for example by hydrogen, to form a composite comprising the metal (Cu, Cu—Co, Cu—Ni) and metal oxide, here Cr2O3. Typically, the composite oxides so formed comprise approximately spherical nanoparticles, and the reduced composites are nanoparticles comprising very small particles of the metal within a network of the oxide, Cr2O3.
