| 摘 要： | 采用浸渍法制备了Al2O3负载的5种过渡金属氧化物催化剂,考察了它们在常温下催化臭氧氧化甲苯的性能,并运用程序升温还原、程序升温氧化、N2吸附-脱附和X射线光电子能谱对催化剂进行了表征.结果表明,NiO/Al2O3,CoO/Al2O3和MnO2/Al2O3催化剂上活性氧中心数量较少,臭氧与甲苯转化率较高;而Fe2O3/...

| Abstract: | Five kinds of transition metal oxides supported on alumina and prepared by wetness impregnation were evaluated for the catalytic ozonation of toluene at room temperature and characterized by temperature-programmed reduction,temperature-programmed oxidation,N2 adsorption-desorption,and X-ray photoelectron spectroscopy.The catalysts with a lower reduction temperature and less H2 consumption showed a higher efficiency for ozone and toluene decomposition,such as NiO/Al2O3,CoO/Al2O3,and MnO2/Al2O3,while lower ef... |
