Using Zn(NO3)2·6H2O and(C6H9NO)n as raw materials,the reaction temperature at 80 ℃and reaction time for 8 h,nano-ZnO powder was prepared by the method of calcining co-precipitation at 500 ℃. The average radius of nano ZnO was 32 nm. Under the UV light,methyl orange in aqueous solu-tion can quickly be decomposed by ZnO catalyst. The effects of amount of catalyst,light time and pH val-ue on photocatalytic degradation of methyl orange were discussed.
