Abstract

The influence of lanthanum (La) doping on the performance of 37 wt Cu/ZnO catalysts for the low temperature water-gas shift (LT-WGS) reaction was investigated. The presence of La decreased the support (ZnO) crystallite size as well as Cu (metal) dispersion on the catalyst surface. A 2.3 wt La loading improved catalyst performance compared with the neat Cu/ZnO system. Beyond this loading the activity decreased substantially. Additionally, 2.3 wt La acted to considerably stabilize catalyst activity compared with the neat system. The activity and stability findings suggest metallic Cu is not responsible for LT-WGS activity by this catalyst.
