Abstract :Herein, titanium insert ignore into journalissuearticles values(Ti3+); self-doped strontium titanate insert ignore into journalissuearticles values(SrTiO3);, so-called blue SrTiO3, with a bandgap of 2.6 eV and favorable photocatalytic characteristics was fabricated through a facile and effective method. For electrochemical investigations, the electrophoretic deposition was applied to produce SrTiO3 thin films on insert ignore into journalissuearticles values(fluorine-doped tin oxide); FTO conductive substrates. The electrophoretic voltage of 20 V and a process duration of 10 min were optimized to reach transparent and uniform coatings on FTO. The blue SrTiO3 reveals lower resistance insert ignore into journalissuearticles values(charge transfer resistance of 6.38 Omega cminsert ignore into journalissuearticles values(-2);); and higher electron mobility insert ignore into journalissuearticles values(current density value of 0.25 mA cminsert ignore into journalissuearticles values(-2);); compared to a pure SrTiO3 electrode. These findings may provide new insights for developing high-performance visible light photocatalysts.
