In this work, ZIF-67 derivative Co3S4 with diamond dodecahedron structure was firstly synthesized via a series of reactions, and ZnIn2S4@Co3S4 heterostructures with adjustable band gaps were successfully obtained through a simple hydrothermal method. Consequently, ZnIn2S4@Co3S4 heterostructures have significantly enhanced visible light absorption and improved photocatalytic efficiency, among which the ZC-5 composite exhibits the highest photocatalytic hydrogen production rate up to 4261 μmol g−1 h−1 under simulated sunlight, to be approximately 4.8 times higher than that of pure ZnIn2S4. The enhanced photocatalytic activity can be attributed to faster electron transfer and more efficient electron–hole pairs separation derived from the heterostructures which form at the interface between Co3S4 and ZnIn2S4. Thus, this study provides a good strategy for photocatalytic hydrogen production without precious metals using heterostructures.

ZIF-67衍生的ZnIn2S4@Co3S4颗粒的合成用于光催化制氢
本工作首先通过一系列反应合成了具有金刚石十二面体结构的ZIF-67衍生物Co 3 S 4 ,并通过简单的水热法成功获得了带隙可调的ZnIn 2 S 4 @Co 3 S 4异质结构。因此,ZnIn 2 S 4 @Co 3 S 4异质结构显着增强了可见光吸收并提高了光催化效率,其中ZC-5复合材料的光催化产氢速率最高,可达4261 μmol g -1 h -1在模拟阳光下,比纯 ZnIn 2 S 4高约 4.8 倍。增强的光催化活性可归因于更快的电子转移和更有效的电子-空穴对分离,这些异质结构源自在 Co 3 S 4和 ZnIn 2 S 4之间的界面处形成的异质结构。因此,本研究为使用异质结构的无贵金属光催化制氢提供了一种很好的策略。
