Effect of Precursor Ammonia on Photocatalysis of Flower-Like ZnO Microstructures Prepared by Microwave Method
Flower-like ZnO was prepared by using a simple and efficient microwave method in different amount of ammonia. The structure, morphology and optical properties of the products were characterized by XRD, SEM and PL. It was found that ZnO prepared by this method was micro dimension. Flower-like structure was consisted of a series of the thick bottom and thin top nanorods; photoluminescence showed a strong green emission peak. Photocatalytic meas- ure showed that ZnO had a strong function of degradation on methyl orange, and the degradation rate is about 95% after 1 hour. The amount of ammonia had effects on structure and morphology of ZnO, but had no significant effects on pho- toluminescence and photocatalysis.
