Abstract
The g-Al2O3 supported nano-ZnO was prepared by impregnating g-Al2O3 with zinc-ammonia solution. The as-prepared samples were analyzed by XRD, SEM and BET. Phenol was used as a probe to evaluate the photocatalytic activity of the g-Al2O3 supported nano-ZnO. The results indicate that ZnO was successfully adsorbed on the surface of g-Al2O3 with a particle size of 7.4 nm. The surface area and pore volume of g-Al2O3 itself and g-Al2O3 supported nano-ZnO were 150.82, 106.32 m2/g and 0.67, 0.47 cm3/g, respectively. The photodegradation rates showed that the photocatalytic performance of ZnO/g-Al2O3 composites was better than that of ZnO. The influence of dosage of the ZnO/g-Al2O3 composites and initial concentration of phenol on the photocatalytic performance were investigated. The results showed that the optimum ZnO/g-Al2O3 composites dosage was 0.4 g for 100 mL phenol solution and the degradation rate was decreasing with the initial concentration of phenol enhancement. Besides, the repeatability of ZnO/g-Al2O3 composites was also investigated in this work.
