Constructing heterostructures and designing excellent structures to simulate natural photosynthesis are effective ways to efficiently and selectively convert CO₂ into products with high energy. Herein, a novel 0D/3D heterostructure composed of Cd_0.5Zn_0.5S quantum dots and CdIn₂S₄ nano-octahedron was resoundingly fabricated via a simple solvothermal–coprecipitation method. The optimal yields of CO₂ photoreduction to CO and CH₄ over the Cd_0.5Zn_0.5S/CdIn₂S₄ composite material could reach up to 14.07 and 4.23 μmol/g/h, respectively, which was primarily due to the synergistic effect of the 0D/3D heterostructure and unique morphology, thus accelerating the transfer of light-induced carriers. In addition, the as-fabricated composite exhibited excellent stability and weaker photocorrosion. Hence, this work could provide a simple and efficient route for the design and construction of photocatalysts with superior activity for CO₂ photoreduction.

Cd0.5Zn0.5S 量子点改性 CdIn2S4 纳米八面体作为 CO2 光还原的 0D/3D 杂化异质结

构建异质结构和设计优良的结构来模拟自然光合作用，是将 CO ₂高效、选择性地转化为高能产物的有效途径。在此，通过简单的溶剂热-共沉淀法制备了一种由 Cd _0.5 Zn _0.5 S 量子点和 CdIn ₂ S ₄纳米八面体组成的新型 0D/3D 异质结构。Cd _0.5 Zn _0.5 S/CdIn ₂ S ₄上CO _{2 光}还原成CO和CH ₄的最佳产率复合材料可分别达到 14.07 和 4.23 μmol/g/h，这主要是由于 0D/3D 异质结构和独特形态的协同作用，从而加速了光诱导载流子的转移。此外，制造的复合材料表现出优异的稳定性和较弱的光腐蚀。因此，这项工作可以为设计和构建具有优异CO _{2 光}还原活性的光催化剂提供一条简单有效的途径。
