Summary The imidazolium salt zeolite framework (ZIFs) organometallic framework materials have the advantages of high stability and controllable structure and are excellent materials for preparing photocatalytic semiconductors. In this study, the regular dodecahedron material ZIF‐67 was used as the substrate, and the intermediate was calcined after the substrate adsorbed Co‐based metal clusters to obtain Co3O4 with a hollow double‐shell structure. Through SEM and fluorescence detection, it can be seen that the Co3O4 material obtained by this method not only has a unique spatial morphology but also shows a strong light absorption performance and a high charge transfer rate. In addition, graphite‐like phase carbon nitride (g‐C3N4), as a traditional catalyst, has been unable to move toward industrialization due to its low electron utilization and light absorption properties. So here, the composite catalyst CNCO‐x (x = 1, 2, 2, 3, 4, and 5) was prepared by simply anchoring Co3O4 and g‐C3N4 to improve the catalytic performance of g‐C3N4. The results show that the introduction of Co3O4 not only improves the electron utilization of g‐C3N4 but forms a charge transfer bridge channel (p‐n heterojunction) after contact between the two, which effectively promotes the rapid transfer of photoelectrons between the contact interfaces. Finally, when the amount of Co3O4 introduced is 15%, the amount of hydrogen produced in 5 hours can reach 0.163 mmol (3.26 mmol g−1 hour−1), which is 163 times that of pure g‐C3N4.

Cocatalyst materials can promote the separation of photogenerated electron‐hole pairs and accelerate the catalytically active sites of semiconductor photocatalysts. However, it is critical to make low‐cost, noble‐metal‐free materials with high catalytic reactivity, yet this task is extremely difficult to do. Herein, an effective photocatalytic hydrogen generation process has been developed using N‐doped Fe3C (N−Fe3C) nanocages adorned with ultrathin ZnIn2S4 nanosheets produced from a dual metal organic framework. In addition, the highly porous hybrid structure developed gives a large number of active sites for catalytic reduction events, and light scattering can be used to better capture visible light. Due to their improved solar‐driven hydrogen evolution rate (9,600 μmol h−1 g−1) and apparent quantum efficiency (3.6 %), these structures are superior to those of Pt noble‐metal co‐catalytic systems and ZnIn2S4‐based nanohybrids, which were previously reported.
