β-Bi2O3 nanosheets were synthesized by the hydrothermal method with Bi(NO3)3· 5H2O and aquafortis as raw material,and added strong aqua ammonia as mineralizer. The materials were characterized by XRD and SEM,analysed the impact of experimental parameters on composi-tion and morphology of the samples,and evaluated the photocatalytic performance of the sample. The results showed theβ-Bi2O3 nano-sheets has high catalytic activity to methyl orange photocatalyt-ic degradation.
