Preparing BiOI photocatalyst for degradation of methyl blue in wastewater

Photocatalytic oxidation on semiconductors is a green and friendly route to deal with environmental issues. Herein, a novel C/BiOIdetect photocatalyst was prepared by one-step hydrothermal method, and this nano composite exhibited excellent photocatalytic degradation performance under visible light irradiation. The substantially increased visible light absorption and separation of photoinduced carriers were attributed to the high photocatalytic performance. Moreover, the C/BiOIdefect also shows outstanding adsorption capacity and photochemical stability, which are also extremely important for practical application.
