Abstract:

Three-dimensional WO3·0.33H2O hierarchical microstructures consisting of nanorods have been successfully constructed through a facile hydrothermal route, employing sodium tungstate and dodecylbenzenesulfonic acid(DBSA) as precursors without the assistance of any additives. Remarkably, DBSA not only acts as a reagent to provide H+ but also serves as a surfactant to tailor the morphology of the as-synthesized products. The hierarchically-structured WO3·0.33H2O displays a strong structure-enhanced photocatalytic activity for the degradation of rhodamine B(RhB) under visible light irradiation, and the degradation ratio of RhB is 100% and is still kept at a high degradation ratio after using 5 times.

Key words: tungsten trioxide hydrate, dodecylbenzenesulfonic acid, three-dimensional hierarchical microstructure, hydrothermal synthesis, photocatalytic degradation
