Tungsten trioxide (WO3) is known as a visible light responsive photocatalyst, but its photocatalytic activity is relatively low, as compared to that of anatase titanium dioxide (TiO2). To enhance the activity, high specific surface areas are necessary. In this study, WO3 particles with a hierarchical architecture, which was assemblies of spherical particles 20 - 30 nm in diameter, were synthesized by the solvothermal method. The hierarchical WO3 particles had high specific surface areas and their photocatalytic activity was found to be 2.5 times higher than that of the commercial WO3.
