W-based semiconductor materials usually have small energy gap and display good visible light ab-sorption and high photocatalytic activity, which have attracted much attention recently. Moreover, their struc-ture, morphology, and surface area can be regulated easily by different synthesis methods. This paper summa-rizes recent research progress of W-based semiconductor photocatalyts, including tungsten oxide, tungstate, doped tungstate, composites and etc. The relationships between structure and photocatalytic performance are analyzed from the view of photocatalytic principle, morphology, specific surface area and energy gap. Finally, the research direction and prospect of W-based semiconductor photocatalyts are suggested.
