摘要: Abstract Cu-Co bi-metal catalysts derived from CuO/LaCoO 3 perovskite structure were prepared by one-step citrate complexing method, and the evolution reaction to 2 C/La O CO under H pretreatment was investigated techniques of XRD, TPR TEM. The results suggest that a much higher dispersion copper significantly enhanced reduction cobalt, stronger interaction between cobalt ions in LaCoO particles led formation bi-metallic reduced enrichment Co on surface bimetallic particles. highly active selective for alcohol synthesis syngas due presence copper-modified C species.
