Abstract The electronic transmission mode can effectively influence the photogenerated electron-hole separation efficiency, which further influence the photocatalytic hydrogen production performance. Herein, we synthesized a CeO2/ZnIn2S4 composite photocatalyst having a 0D/2D heterojunction by facile solvothermal and room temperature precipitation methods. The successful construction of the heterojunction was demonstrated by XRD and XPS. Meanwhile, the interesting findings shows that the 0D “chess” CeO2 compounded on the 2D “checkerboard” ZnIn2S4 in SEM and TEM. The ESR test of O2− and OH demonstrates the photocatalytic mechanism of Z-scheme electron transport in the catalyst. The highest hydrogen production rate of the catalyst reaches 847.42 μmol·g−1·h−1. This work provides a simple and effective strategy to achieve a rationally design photocatalyst for efficient, stable and cost-effective solar hydrogen production applications.

0D/2D CeO2/ZnIn2S4 Z 型异质结用于可见光驱动的光催化 H2 演化

摘要 电子传输模式可有效影响光生电子-空穴分离效率，进而影响光催化制氢性能。在此，我们通过简便的溶剂热和室温沉淀法合成了具有 0D/2D 异质结的 CeO2/ZnIn2S4 复合光催化剂。XRD和XPS证明了异质结的成功构建。同时，有趣的发现表明，在 SEM 和 TEM 中，0D“棋盘”CeO2 复合在二维“棋盘”ZnIn2S4 上。O2− 和 OH 的 ESR 测试证明了催化剂中 Z 型电子传输的光催化机制。该催化剂的最高产氢率达到847.42 μmol·g-1·h-1。
