【摘要】 采用空气氧化湿法制备了含Ｚｎ、Ｎｉ、Ｃｏ 的尖晶石型铁酸盐。运用ＸＲＤ、ＩＲ、ＵＶ－ＤＲＳ和ＴＰＲ等方法对所制备的样品进行了表征。研究了铁酸盐的化学组成、结构和氧化还原性质。考察了铁酸盐对二氧化碳选择性氧化乙苯制苯乙烯的催化性能，并讨论了催化剂的结构、组成对反应活性的影响以及二氧化碳的作用。更多还原

【Abstract】 The spinel ferrites were prepared by the wet method of air oxidation and characterized by XRD, IR, UV DRS and TPR method. The catalytic activity of oxidative dehydrogenation of ethylbenzene to styrene with carbon dioxide over the spinel ferrites was studied. And the relationships among catalytic activity, composition, structure and the action of carbon dioxide were also discussed.$$$$更多还原
