中文摘要: 采用3种不同的顺序制备了镧镍复合氧化物前驱体后，再在这3种物质上用等体积浸溃法制备了一系列Cu／La2O3-NiO催化剂。用XRD、TEM分别对催化剂表面结构、表面形貌进行了表征，以CO2和H2O光催化合成甲醇反应为探针反应研究了不同的制备方法对催化剂性能的影响。结果表明：先混合碾磨并一起焙烧后再处理的Cu／La2O3-NiO催化剂，其光催化活性最强，而先分开碾磨后一起焙烧再处理的催化剂光催化活性其次，而机械混合后再一起处理的催化剂对目的反应没有光催化活性。其中0．5％Cu／La2O3-NiO催化剂的催化效果最好。
Abstract:Three different La--Ni mixed oxides are synthesized with three different sequences, then a series of Cu/La2O3-NiO catalysts are prepared by the same volume soakage method. The surface appearances and microstructure of catalysts have been analyzed by XRD and TEM. The effects of preparing method on the properties of catalyst are discussed by means of the reaction of methanol through the photocatalysis synthesis way using CO2 and H2O. The results show that the 0.5%Cu/La2O3-NiO catalyst is the most useful.
