摘　　要： 以共沉淀法制备了吸附树脂负载的双组分金属氧化物催化剂Ｃｏ—Ｏ—Ｃｒ／Ｄ３５２０，考察了其对四氢萘催化氧化的性能，其性能显著优于单组分Ｃｏ３Ｃ４／Ｄ３５２０或Ｃｒ２Ｏ３／Ｄ３５２０。萘满酮的收率达９０％。用Ｘ射线衍射法（ＸＲＤ）、Ｘ射线光电子能谱法（ＸＰＳ）、顺磁共振法（ＥＰＲ）研究了催化剂结构，给出了活性中心示意图，并对催化剂的高活性给予了解释。 Adsorption resin (D3520)-supported bimetallic oxides catalyst (Co-O-Cr/D3520) was prepared by co-precipitation. Its calalytic ability for the oxidation of tetralin was studied. The yeild of α-tetralone was up to 90%,the ability of Co-O-Cr/D3520 catalyst was obviously better than that of the Co3O4/D3520 or Cr2O3/D3520 catalyst. The structure of catalysts was characterized by XRD、XPS、EPR etc. The diagram of the active center was given. This paper also explained the high activity of Co-O-Cr/D3520.
