摘要: Summary Raney copper catalysts prepared by leaching have been doped with precipitated zinc oxide using a novel preparation technique. The resulting maintained approximately the same surface area varying coverage of oxide. activity has tested for methanol synthesis, forward and reverse water gas shift steam reforming. Methanol synthesis increases content, while reforming reaction decrease increasing content. results can be explained in terms model which synergy between relates to formation H atoms on followed migration
