Abstract

Abstract

A series of supported CuO/La_1−xCe_xCrO₃ catalysts were prepared by the sol-gel method and the effect of Ce doping in the A site on their structure, properties and catalytic performance in the steam reforming of methanol were investigated. The results indicate that the Ce doping impacts mainly on the reduction performance of CuO and the interaction between the perovskite support and CuO, which in turn influences the catalytic performance of CuO/La_1−xCe_xCrO₃ in methanol steam reforming. In particular, the CuO/La_0.8Ce_0.2CrO₃ catalyst demonstrates adequate performance in methanol steam reforming; over it, the methanol conversion reaches 100% under 280 °C, water/methanol molar ratio of 1.2 and methanol gas hourly space velocity of 800 h⁻¹.
