  • Abstract
    Nanoporous tungsten oxide (WO3) with pore size of about 80 nm has been fabricated by anodization in a 1 M Na2SO4 solution with 0.5 wt% NaF (pH 4.0) at the anodization voltage of 40 V. The photoelectrochemical properties and photocatalytic activity of the nanoporous WO3 film are investigated under visible light. The results show that the WO3 nanoporous structure has better photoactivity than the plane structure under visible light irradiation and is a potential photocatalyst to decompose contamination in water under visible light.
