520			\|a In recent years, defective TiO<sub<2</sub<-based composite nanomaterials have received much attention in the field of photocatalysis. In this work, TiB<sub<2</sub< was used as a precursor to successfully prepare Ti<sup<3+</sup< defective TiO<sub<2</sub< (TiO<sub<2</sub<-B) with a truncated bipyramidal structure by a one-step method. Then, the SnS<sub<2</sub< nanosheets were assembled onto the as-prepared TiO<sub<2</sub<-B through simple hydrothermal reaction. TiO<sub<2</sub<-B exhibits strong visible light absorption properties, but the recombination rate of the photo-generated electron-hole pair was high and does not exhibit ideal photocatalytic performance. Upon introducing SnS<sub<2</sub<, the heterojunction catalyst SnS<sub<2</sub<-Ti<sup<3+</sup< defective TiO<sub<2</sub< (SnS<sub<2</sub</TiO<sub<2</sub<-B) not only possesses the strong light absorption from UV to visible light region, the lowest photo-generated charge recombination rate but also achieves a more negative conduction band potential than the reduction potential of CO<sub<2</sub< to CO, and thereby, exhibits the significantly enhanced selectivity and yield of CO in photocatalytic CO<sub<2</sub< reduction. Notably, SnS<sub<2</sub</TiO<sub<2</sub<-B produces CO at a rate of 58 µmol·h<sup<−1</sup<·g<sup<−1</sup< with CO selectivity of 96.3% under visible light irradiation, which is 2 and 19 times greater than those of alone TiO<sub<2</sub<-B and SnS<sub<2</sub<, respectively. Finally, a plausible photocatalytic mechanism on SnS<sub<2</sub</TiO<sub<2</sub<-B was proposed that the electron transfer between TiO<sub<2</sub< and SnS<sub<2</sub< follows the Z-scheme mode. Our results present an effective way to gain highly efficient TiO<sub<2</sub< based photocatalysts for CO<sub<2</sub< reduction by combining different modification methods of TiO<sub<2</sub< and make full use of the synergistic effects.

In this work, TiB<sub<2</sub< was used as a precursor to successfully prepare Ti<sup<3+</sup< defective TiO<sub<2</sub< (TiO<sub<2</sub<-B) with a truncated bipyramidal structure by a one-step method. Then, the SnS<sub<2</sub< nanosheets were assembled onto the as-prepared TiO<sub<2</sub<-B through simple hydrothermal reaction. TiO<sub<2</sub<-B exhibits strong visible light absorption properties, but the recombination rate of the photo-generated electron-hole pair was high and does not exhibit ideal photocatalytic performance. Upon introducing SnS<sub<2</sub<, the heterojunction catalyst SnS<sub<2</sub<-Ti<sup<3+</sup< defective TiO<sub<2</sub< (SnS<sub<2</sub</TiO<sub<2</sub<-B) not only possesses the strong light absorption from UV to visible light region, the lowest photo-generated charge recombination rate but also achieves a more negative conduction band potential than the reduction potential of CO<sub<2</sub< to CO, and thereby, exhibits the significantly enhanced selectivity and yield of CO in photocatalytic CO<sub<2</sub< reduction.

abstract	In recent years, defective TiO<sub<2</sub<-based composite nanomaterials have received much attention in the field of photocatalysis. In this work, TiB<sub<2</sub< was used as a precursor to successfully prepare Ti<sup<3+</sup< defective TiO<sub<2</sub< (TiO<sub<2</sub<-B) with a truncated bipyramidal structure by a one-step method. Then, the SnS<sub<2</sub< nanosheets were assembled onto the as-prepared TiO<sub<2</sub<-B through simple hydrothermal reaction. TiO<sub<2</sub<-B exhibits strong visible light absorption properties, but the recombination rate of the photo-generated electron-hole pair was high and does not exhibit ideal photocatalytic performance. Upon introducing SnS<sub<2</sub<, the heterojunction catalyst SnS<sub<2</sub<-Ti<sup<3+</sup< defective TiO<sub<2</sub< (SnS<sub<2</sub</TiO<sub<2</sub<-B) not only possesses the strong light absorption from UV to visible light region, the lowest photo-generated charge recombination rate but also achieves a more negative conduction band potential than the reduction potential of CO<sub<2</sub< to CO, and thereby, exhibits the significantly enhanced selectivity and yield of CO in photocatalytic CO<sub<2</sub< reduction. Notably, SnS<sub<2</sub</TiO<sub<2</sub<-B produces CO at a rate of 58 µmol·h<sup<−1</sup<·g<sup<−1</sup< with CO selectivity of 96.3% under visible light irradiation, which is 2 and 19 times greater than those of alone TiO<sub<2</sub<-B and SnS<sub<2</sub<, respectively. Finally, a plausible photocatalytic mechanism on SnS<sub<2</sub</TiO<sub<2</sub<-B was proposed that the electron transfer between TiO<sub<2</sub< and SnS<sub<2</sub< follows the Z-scheme mode. Our results present an effective way to gain highly efficient TiO<sub<2</sub< based photocatalysts for CO<sub<2</sub< reduction by combining different modification methods of TiO<sub<2</sub< and make full use of the synergistic effects.
