The role of copper in catalytic performance of a FeCuAlO catalyst for water gas shift reaction

A FeCuAlO water gas shift catalyst with a Fe:Cu atomic ratio of 4:1 upon pretreatment at 350 C in H 2 exhibits a conversion higher than a physical mixture of FeAlO and CuAlO by 40% over a temperature range of 300 C450 C. In situ ambient pressure X-ray photoelectron spectroscopy studies suggest that... Full description

description: A FeCuAlO water gas shift catalyst with a Fe:Cu atomic ratio of 4:1 upon pretreatment at 350 C in H 2 exhibits a conversion higher than a physical mixture of FeAlO and CuAlO by 40% over a temperature range of 300 C450 C. In situ ambient pressure X-ray photoelectron spectroscopy studies suggest that the surface region of FeCuAlO was restructured into a double-layer structure consisting of a surface layer of Fe 3 O 4 and a metallic Cu layer below it upon pretreatment at 350 C. The strong metal (Cu)oxide (Fe 3 O 4 ) interface effect of this double layer structure enhances the catalytic activity of Fe 3 O 4 in WGS.
