Synthesis of NiO/Bi<sub>2</sub>O<sub>3</sub> composite nanosheets and their photocatalytic CO<sub>2</sub> reduction performance
The development of catalysts for photocatalytic reduction of CO<sub>2</sub> is of great significance for addressing the excessive emission of CO<sub>2</sub>. In this study, we designed and synthesized a series of NiO/Bi<sub>2</sub>O<sub>3</sub> composite nanoflakes and used them for photocatalytic CO<sub>2</sub> reduction. Among them, Ni/Bi-30 exhibits the best CO<sub>2</sub> reduction activity with a CO generation rate of 10.2 μmol g<sup>-1</sup> h<sup>-1</sup> and a selectivity of 100%. The mechanism study indicates that the Z-type heterojunction formed between NiO and Bi<sub>2</sub>O<sub>3</sub> promotes the separation of photogenerated carriers and enhances the photocatalytic effect.
