Abstract
The copper-cobalt catalysts for alcohol synthesis were prepared and studied by ESCA techniques (XPS and XAES) and TPR. The valence states of the surface elements were investigated for Co−Cu−Y based catalysts, and it was found that there were some reoxidation during the reaction. From the XPS and XAES results, strong interactions between copper and cobalt in the samples were presented, in agreement with the TPR experiments. The interacted copper-cobalt units could be the active sites for higher alcohol synthesis.
