摘要

光催化还原CO2催化剂的开发对于解决CO2的过量排放具有重要意义。在本研究中，我们设计并合成了一系列NiO/Bi2O3复合纳米片，并将其用于光催化CO2还原。其中，Ni/Bi-30的CO还原活性最好，CO生成速率为10.2 μmol g-1 h-1，选择性为100%。机理研究表明，NiO与Bi2O3之间形成z型异质结，促进了光生载流子的分离，增强了光催化效果。

Synthesis of NiO/Bi2O3 composite nanosheets and their photocatalytic CO2 reduction performance

The development of catalysts for photocatalytic reduction of CO₂ is of great significance for addressing the excessive emission of CO₂. In this study, we designed and synthesized a series of NiO/Bi₂O₃ composite nanoflakes and used them for photocatalytic CO₂ reduction. Among them, Ni/Bi-30 exhibits the best CO₂ reduction activity with a CO generation rate of 10.2 μmol g⁻¹ h⁻¹ and a selectivity of 100%. The mechanism study indicates that the Z-type heterojunction formed between NiO and Bi₂O₃ promotes the separation of photogenerated carriers and enhances the photocatalytic effect.
