![عکس صفحه اول مقاله: Towards atomic level vanadium doping of TiO2 via liquid-phase atomic layer deposition Towards atomic level vanadium doping of TiO2 via liquid-phase atomic layer deposition](/preview/png/41061.png)
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.
