摘　　要：在以肉桂醛选择性加氢制肉桂醇的反应中,通过反应筛选出助剂性能优异的助剂,并确定助、主剂的最佳配比为0.2(mol/mol).结合催化剂表征手段结果发现:Fe对Co3O4晶体的完整程度产生影响并能导致晶体缺陷数增加,Fe引入使催化剂在载体硅藻土表面分散性更好,分散的单层性更明显,负载在硅藻土上催化剂的晶粒粒径有变小趋势.Through reaction to select the best performance additive and identify the best ratio of additive and main agent is 0.2 （mol/mol）, cinnamahtehyde selective hydrogenation to cinnamyl alcohol was studied. And the means of catalyst characterization were found that Fe effects on the perfect degree of crystal Co3O4 and leads to quantity of crystal defect improved. The Fe makes catalyst on diatomite surface dispersion better, and dispersion of single layer crystal is more obviously. The loading catalyst is the trend that the crystal each grain of catalyst on the diatomite diminishes.
