dc.description.abstract | A photocatalyst for visible light irradiation was prepared by simultaneously doping SrTiO3 with F- anion and Rh3+ and Ta5+ cations for the first time through a spray pyrolysis process. The ternary doping of F- contributed to the reduction of Ti4+ and Rh4+ to Ti3+ and Rh3+, respectively, by generating extra electron in the lattice. The partially substituted structure of the photocatalyst could be expressed as Sr(Ti1-2x-z4+Tiz3+Rhx-y3+Rhy4+Tax5+) (O3-w2-F- w). The doping of F- into SrTiO3:Rh/Ta increased the photocatalytic hydrogen evolution rate to 4123.7 mu molg(-1)h(-1) (quantum efficiency: 6.60%) under visible light irradiation, which was 1.93 times higher than that of SrTiO3:Rh/Ta. The optimum composition of dopants for maximum hydrogen evolution rate was Rh (0.15 mol%), Ta (0.15 mol%), and F (6.0 mol%). (C) 2016 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
