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,由环己烷直接氧化制得环己酮。用电子衍射、漫反射紫外可见吸收光谱等方法测定了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。Cyclohexanone was prepared from cyclohexane by the photocatalytic oxidation under the mild conditions or normal temperature, pressure and neutral medium. The microstructures of the TiO_2 powder catalysts were determined by the electron diffraction and other methods. The dependence of the catalytic activities on the TiO_2 isomers was proved. It was found that the (010) face of anatase may be the activated crystal face.
