Synthesis of Bi₂MoO₆/BiOI Composites for Visible Light Driven Photocatalytic Degradation of Methylene Blue

Bi2MoO6/BiOI composites were synthesized by solvothermal method and photocatalytic performances were evaluated by degrading methylene blue (MB). Experiment results show that Bi2MoO6/0.5BiOI has the best photocatalytic efficiency for eliminating 92% MB in 2 h under the excitation of visible light. Such superior photocatalytic performance is due to the significantly enhanced ability to absorb visible light and separated efficiency of photogenerated electrons and holes.
