Photocatalytic oxidation of glycerol at ambient conditions has been investigated with the use of Zinc oxide photocatalysts. Zinc oxide nanorods were prepared via a simple hydrothermal method using zinc nitrate and sodium hydroxide in the solution pH of 7, 8 and 9. The samples prepared in this way were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), Brunauer-Emmett-Teller (BET) and ultraviolet–visible spectroscopy (UV–vis). The pH of the solution is 7, the sample contains zinc hydroxide nitrate hydrated. When the pH of solution was adjusted to 8 and 9, the samples consisted of pure hexagonal wurtzite ZnO without impurity detection. The influence of solution pH on hydrogen formation was investigated. The wurtzite ZnO nanorods synthesized in a solution with pH 9 are considered promising photocatalysts for hydrogen production under xenon radiation. 相似文献
