Synthesis of C-In2O3/BiOI composite and its enhanced photocatalytic degradation for methyl blue

Abstract In this work, C-In 2 O 3 /BiOI composite is synthesized and used as a high performance photocatalyst for photocatalytic degradation of methyl blue (MB) in wastewater. The C-In 2 O 3 /BiOI composites demonstrate 5 times higher photocatalytic performance than the pristine BiOI and In 2 O 3 for MB degradation under the irradiation of visible light. Furthermore, the C-In 2 O 3 /BiOI composites have excellent cycling stability. Such enhanced photoactivity is due to the significantly enhanced separation efficiency of photogenerated. This work provides some significance in the design and construction of environmentally benign catalysts with excellent photocatalytic degradation of toxic pollutants.
