| Abstract | ||
| CoO-ZnO catalyst was prepared by using the coprecipitation method, by adding sodium bicarbonate to cobalt and zinc nitrates solution until pH equal to 8.The resulted cobalt and zinc bicarbonate was calcinated at 773 Kº for 4 hours. Then the catalyst was characterized by chemical analysis, and X-Ray Diffraction Teqnique(XRD).The activity of CoO-ZnO catalyst was examinated in the photocatalytic oxidation of benzyl alcohol, to the corresponding benzaldehyde,at different times, and temperatures. The results showed that the activation energy for CoO-ZnO catalyst equal 16 kJmol-1 , it is lower than that, for ZnO which equal to 21 kJmol-1. | ||
