Abstract

Abstract The catalytic activities of the low-temperature water–gas-shift (LT-WGS) reaction were investigated for Al2O3-supported Cu catalysts containing CrOx, MnOx, FeOx, CoOx, NiOx, or ZnO. The catalytic activity of Cu/Al2O3 catalyst at 423 K was improved by the small addition of transition-metal oxide. In particular, Cu/Al2O3 with CoOx showed the highest activity among the supported Cu catalysts used in this study.
