摘要：

In this paper, we successfully fabricate Ti(IV) doped WO3 nanocuboids with controlled Ti(IV) contents through a facile, mild, aqueous-phase route. The characterizations clearly exhibit the optimum amount of the Ti(IV) dopant in under these conditions. The obtained photocatalyst shows excellent visible-light-driven photocatalytic performance. It can decompose an organic dye within 70 min under visible-light irradiation. Such a large activity enhancement probably arises from the change of band structure. The results provide an efficient route for the design of photocatalysts with improved visible-light-driven photocatalytic activity as well as a promising material for use in solar cells, nanodevices, and other applications.
