It is important to prepare a visible-light responsive photocatalyts, which has enhanced absorbance in the range of visible-light. In addition, metal nanoparticles deposited on TiO2 induced the localized surface plasmon resonance (LSPR) effect of Au nanoparticles (AuNPs), and thus enhanced the photocatalytic activity. Herein, TiO2 microrods with nano-branch (B-TiO2) on the fluorine-doped tin oxide glass (FTO) was prepared by hydrothermal method, and AuNPs was deposited on the B-TiO2. Its photocatalytic activity was evaluated by reduction of toxic Cr(VI) to less-toxic Cr(III) under visible-light irradiation. AuNPs/B-TiO2/FTO was successfully photocatalytic reduced target ions and Cr(III) ions were also removed from aqueous phase. (C) 2019 The Korean Society of Industrial and Engineering Chemistry.
