As a typical member of sulfide family, ZnIn₂S₄ bears impressive activity in photocatalysis. Nonetheless, egregious recombination of photo-excited electron and hole pairs confines its practical usage. In this study, PCN-224, a metal organic framework (MOF) composed of porphyrin linkers and Zr clusters, is employed to establish a novel hierarchical structured ZnIn₂S₄@PCN-224 via a solvothermal method. These as-prepared composites are further evaluated by visible-light-driven photocatalysis and able to present steady performance. The optimized ZnIn₂S₄@PCN-224 has a hydrogen production rate of 0.284 mmol h⁻¹ in absence of Pt, higher than many contrastive ZnIn₂S₄-based photocatalysts even in assistance of Pt cocatalyst. Besides, it is able to dominate the degradation of tetracycline hydrochloride (TCH), giving 99.9 % pollutant removal within 60 min, about 4.7 times higher than that catalyzed by ZnIn₂S₄. It is supposed that the great improvement in photocatalysis is ascribable to the establishment of Z-scheme junction between ZnIn₂S₄ and PCN-224.

作为硫化物家族的典型成员，ZnIn ₂ S ₄在光催化中具有令人印象深刻的活性。但是，光激发电子和空穴对的剧烈结合限制了其实际应用。在这项研究中，PCN-224是由卟啉连接子和Zr团簇组成的金属有机骨架（MOF），用于通过溶剂热方法建立新型的分层结构ZnIn ₂ S ₄ @ PCN-224。这些制备的复合材料可通过可见光驱动的光催化作用进一步评估，并能够表现出稳定的性能。优化的ZnIn ₂ S ₄ @ PCN-224在不存在Pt的情况下具有0.284 mmol h ^-1的氢气产生速率，高于许多对比ZnIn₂ S ₄基光催化剂，甚至在Pt助催化剂的协助下。此外，它能够控制四环素盐酸盐（TCH）的降解，在60分钟内去除99.9％的污染物，比ZnIn ₂ S ₄催化的高4.7倍。据推测，光催化的极大改善归因于在ZnIn ₂ S ₄和PCN-224之间建立Z方案结。
