In this study, supported nonmetal (boron) doping TiO_2 coating photocatalysts were prepared by chemical vapor deposition (CVD) to enhance the activity under visible light irradiation and avoid the recovering of TiO_2. Boron atoms were successfully doped into the lattice of TiO_2 through CVD, as evidenced from XPS analysis. B-doped TiO_2 coating catalysts showed drastic and strong absorption in the visible light range with a red shift in the band gap transition. This novel B-TiO_2 coating photocatalyst showed higher photocatalytic activity in methyl orange degradation under visible light irradiation than that of the pure TiO_2 photocatalyst.
