摘　　要：采用溶剂热法在铜片薄膜表面负载铁、镍以及铁镍合金得到纳米结构薄膜催化剂,并以水合肼还原对硝基苯酚为模型反应来考察其催化性能。主要探究薄膜催化剂在不同温度、催化剂的种类和用量以及氢氧化钠用量条件下催化活性的变化。实验表明将氯化铁和氯化镍以1∶1的摩尔比例混合并加入水杨酸进行反应后制得的纳米铜膜催化剂催化效果最好,而温度和氢氧化钠用量对其催化活性的影响较为明显。在反应温度为30℃、氢氧化钠用量为1.2 g、反应时间为30 min的条件下对硝基苯酚的还原率可达97.5%以上。In this study, metallic Fe, Ni and their alloy thin supported on Cu substrate were prepared by a solvothermal method. Reduction of p-nitrophenol with hydrazine hydrate was applied as a model reaction to investigate the catalytic performance of the film catalysts. The roles of many factors, such as, reaction temperatures, the types and dosage of catalysts, NaOH dosage, in the catalytic process were investigated. Experimental results show that FeNi thin film catalyst, synthesized in the presence of the salicylic acid as a complexant, exhibits the best catalytic activity. When the reaction temperature was 30 ℃, the dosage of sodium hydroxide was 1.2 g, the reaction time was 30 min, the reduction ratio of p-nitrophenol could reach more than 97.5 %.
