| Abstract: | NiO nanosheets were prepared by hydrothermal method, with analysis of its microstructure and morphology by XRD and TEM. Photocatalytic degradation of B -RN solution was studied with NiO nanosheets as catalyst agent under UV lamp. The effect of roasting temperature of catalyst, irradiation time, catalyst dosage, initial concentration of B-RN and used amount of catalyst on decolorization was also investigated. Results showed that NiO nanosheets can degrade B-RN solution effectively, with easy reuse. |
