摘要：
Bismuth oxide was widely studied as an important metal oxide semiconductor. In this paper, a series of alpha-Bi2O3/Fe2O3 with different contents of Fe2O3 were synthesised using a sol-gel method. The photocatalytic performance of composites powder was evaluated using rhodamine B (RhB) as a model pollutant under visible light irradiation (lambda>420 nm). The alpha-Bi2O3/Fe2O3(x) samples present much higher photocatalytic performance than that of pure alpha-Bi2O3. When the composite content is 30 wt-%, the composite shows the best performance which can effectively degrade 85% RhB within 60 min. In addition, the photocatalytic mechanism of this kind of composite photocatalyst was discussed.
