CNTs/TMO复合催化剂对含高氯酸钾烟火药剂分解反应速率的影响

摘要

采用化学沉淀法制备沉积于碳纳米管(CNTs)表面上的CuO、Fe2O3复合催化剂.用光电子能谱(XPS)对复合催化剂进行表征,研究了CuO/CNTs和Fe2O3/CNTs复合催化剂对含高氯酸钾烟火药剂分解反应的影响.结果表明,CuO和Fe2O3颗粒均匀地附着在碳纳米管表面上,Cuo/CNTs和Fe3O3/CNTs复合催化剂能够提高含高氯酸钾烟火药剂的反应速率,复合催化剂对高氯酸钾烟火药剂的催化性能明显优于Fe2O3和CuO混合物的催化性能.%Carbon nanotubes (CNTs) supporting ferric oxide (Fe2O3) and copper oxide (CuO)as composite particles catalyst was prepared by the chemical precipitation method, and characterized by XPS. The effect of Fe2O3/CNTs and CuO/CNTs composite particles catalyst on the decomposition reaction of fireworks containing potassium perchlorate (KP) was studied. The results show that Fe2O3 and CuO were coated uniformly on the surface of carbon nanotubes. The reaction rate of KP adding Fe2O3/CNTs and CuO/CNTs composite particles catalyst was enhanced. Catalytic properties of Fe2O3/CNTs and CuO/CNTs composite particles were superior to that of Fe2O3 and CuO.
