In recent years, Bi2WO6 has entered people’s field of vision as a new, green and safe photocatalyst. It has become a research hot spot because of its narrow forbidden band width and perovskite-like layered structure which can effectively improve the utilization rate of sunlight. Controlling the preparation conditions of the catalyst to control its morphology and thus improve its catalytic performance is one of the main research directions of Bi2WO6. Combining several aspects of Bi2WO6, the morphology and degradation ability of the materials ar...
