Vanadium-doping of TiO2 at the atomic level was achieved via a liquid phase atomic layer deposition (L-ALD) method. UV–vis absorption edge of vanadium-doped TiO2 has been red-shifted ∼55 nm into visible light region. Photocatalytical assessment reveals that the degradation rate of methylene blue (MB) for vanadium-doped TiO2 under visible light illumination was enhanced by up to 500% compared to the undoped TiO2. This improvement was believed to be attributed to the atomic level doping of the L-ALD method.
