摘要
以Bi(NO3)3·5H2O和浓硝酸为原料,加入浓氨水作为矿化剂,采用水热法制备了β-Bi2O3纳米片。研究了制备工艺对纳米片微观形貌的影响,并对样品进行了光催化性能评价。结果显示,β-Bi2O3纳米片对甲基橙的光催化降解具有较高的催化活性。
β-Bi203 nanosheets were synthesized by the hydrothermal method with Bi (NO3)3· 5H20 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 the β-Bi203 nano-sheets has high catalytic activity to methyl orange photocatalyt- ic degradation.
