英文摘要	beta-Bi2O3 nanoparticles with an average grain size of 100 nm were synthesized by a polyacrylamide sol-gel method. Their bandgap energy is obtained by ultraviolet-visible diffuse reflectance spectroscopy is 2.37 eV. beta-Bi2O3/GR composites were fabricated by mixing beta-Bi2O3 nanoparticles and graphene into absolute ethanol solution followed by thermal drying. A transmission electron microscopy observation shows that beta-Bi2O3 nanoparticles are well assembled onto GR sheets. The photocatalytic activity of prepared samples was evaluated by degrading methylene blue under the irradiation of visible light. Compared to bare beta-Bi2O3 nanoparticles, beta-Bi2O3/GR composites exhibit significantly enhanced photocatalytic activity.
