摘　　要：在常温、常压、中性介质等温和条件下,通过光催化新途径,由环已烧直接氧化制得了环已酮。用电子衍射等方法测定二氧化钛半导体粉末光催化剂的微观结构,证实了催化性能与锐钛矿变体有关,发现(010)面可能是活性晶面,提出了可能的反应机理。Cyclohexanone was prepared from cyclohexane by the photocatalytic oxidation und-er the mild conditions of ambient temperature, pressure and neutral medium. The mier-ostructures of the TiO2 powder catalysts were determined by the electron diffraction and other methods. The dependence of the catalytic activities on the TiO2 isomers were proved, It was found that the (010) face of anatasc may be the activated crystal face. The tetative reaction mechanism were proposed.
