Iodine-Deficient BiO I Coupling with Bi O for Degradation of Volatile Organic Compounds under Simulated Sunlight Irradiation.

A photocatalyst with a high separation efficiency of carriers is crucial for the photocatalytic efficient decomposition of volatile organic compounds (VOCs). In this work, a new iodine-deficient BiO I /Bi O photocatalyst was developed through a solvothermal approach coupled with thermal decomposition. The 2 wt % BiO I /Bi O sample demonstrated optimal photocatalytic activity for the degradation of toluene, achieving a 55.
