摘要
以ZnSO4·7H2O和Na2CO3为原料,采用沉淀法制备纳米ZnO粉体。以甲基橙为研究对象,高压汞灯为光源,研究了催化剂用量、甲基橙初始浓度及煅烧温度对甲基橙降解率的影响。
The photocatalyst of nanocrystalline ZnO were prepared by precipitation method with ZnSO4·7H2O and Na2CO3 as raw materials. The photocatalytic degradation of Methyl orange in water was studied in photoreactor with high-pressure mercury lamp as light source and nanocrystalline ZnO as photocatalyst. The effects of the catalyst loading, the initial concentration of methyl orange, pH value and the sintering temperature of ZnO were also investigated.
