Photocatalytic Oxidation of Cyclohexane to Cyclohexanone II. The Electron Diffraction Microstructures and the Photocatalytic Activities of Titanium Dioxides

Cyclohexanone was prepared from cyclohexane by the photocatalytic oxidation under the mild conditions or normal temperature, pressure and neutral medium. The microstructures of the TiO₂ powder catalysts were determined by the electron diffraction and other methods. The dependence of the catalytic activities on the TiO₂ isomers was proved. It was found that the (010) face of anatase may be the activated crystal face.
