| 摘 要： | 采用阳极氧化技术在不锈钢丝网上自生长了一层结构致密的阳极氧化膜,并以此为载体,制备出一种高活性、高稳定性的负载型Ce-Pt-Pd催化剂.考察了该系列催化剂对甲苯、丙酮和乙酸乙酯的氧化活性,并用扫描电镜、X射线光电子能谱和程序升温氧化技术对催化剂进行了表征.结果表明,不锈钢丝网载体表面自生长的氧化物膜十分有利于活性组分的负载,制得的催化剂具有较高的催化燃烧有机化合物的活性和稳定性.

| Abstract: | A catalyst of Ce-Pt-Pd/stainless steel wire meshes was prepared by anodic oxidation techniques, and its catalytic behavior for total oxidation of toluene, acetone, and ethyl acetate was investigated. The catalyst was characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, and O2 temperature-programmed oxidation. The results indicated that the high catalytic activity and stability of the catalyst are caused by taking stainless steel wire meshes as support and whose surface is covered... |
