Progress in the Study of Modification of Bismuth Tungstate-based Photocatalysts
In recent years,the needs and problems in the fields of energy and environment have led to extensive photocatalysis research.Bismuth tungstate(Bi2 WO6)is an excellent photocatalyst because of its non-toxicity,low bandgap energy and easy preparation.In this paper,the modification studies of Bi2 WO6-based photocatalysts are reviewed from the aspects of morphology control,doping and the formation of heterojunction,and the future development is prospected,with a view to providing a reference basis for controlling environmental pollution and promoting sustainable development.
