摘要：

A series of NaBiO3/Bi2O3 composites with different contents of NaBiO3 were synthesized. Their crystalline phases, compositions, light absorption performances and electron-hole separation situations were characterized. Also, their photocatalytic activities were compared by degrading malachite green solution. The results showed that 4.75% NaBiO3/Bi2O3 demonstrated the best photocatalytic activity. Approximately 95.70% of malachite green was degraded after illuminating for 300 min. The photocatalytic mechanism of the heterojunction-structured photocatalyst was put forward as well.
