摘要:
以Bi(NO3)3·5H2O为原料,NaOH为沉淀剂,丙三醇为控制剂,采用水相一步沉淀法在90 ℃的温度下制备了厚度约为5 nm的Bi2O3纳米片.利用X射线衍射(XRD)、扫描电镜(SEM)、紫外-可见(UV-vis)漫反射(DRS)吸收光谱、紫外-可见分光光度计对样品的结构形貌和光催化性能进行了表征和分析.结果表明,所得产物为单斜结构的纳米片,且具有较好的可见光催化性能.
Abstract:
Bi2O3 nanosheets were synthesized by precipitating bismuth nitrate with sodium hydroxide under one-step aqueous process at 90 ℃ in the presence of glycerol. The thickness of Bi2O3 nanosheets was about 5 nm. The crystal structure, morphology and photocatalytic activity of the product were characterized by X-ray diffraction(XRD), scanning electron microscope(SEM), UV-visible diffuse reflectance spectrum(UV-vis DRS)and UV-vis spectrophotometer. The results indicated that the product was nanosheets with monoclinic structure and had better performance on visible light photocatalysis.
