Influence of Preparation Methods on the Performance of Cu/La2O3 Catalysts for Transfer Dehydrogenation of 1-Octanol

Keywords： Cu/La2O3 , 1-octanol , transfer dehydrogenation , 1-octanal

采用沉积-沉淀法(DP)、共沉淀法(CP)和浸渍法(IMP)制备了Cu/La2O3催化剂,并用ICP-AES、BET、XRD、H2-TPR及TEM等对催化剂进行了表征,以1-辛醇转移脱氢制备1-辛醛的反应为探针反应研究了不同的制备方法对Cu/La2O3催化剂性能的影响.结果表明,与采用共沉淀法(CP)和浸渍法(IMP)制备的催化剂相比,沉积-沉淀法(DP)制备的Cu/La2O3催化剂具有更大的比表面积和更高分散度的Cu物种,使得Cu/La2O3催化剂在1-辛醇液相转移脱氢制1-辛醛的反应中具有更好的转移脱氢活性.
