In the recent years, polyoxometalate (POM) encapsulated metal–organic framework (MOF) composites have attracted much attention in photocatalysis. Both POMs and MOFs been attracting immense this area. Furthermore, order to promote charge transfer separation between MOFs, theoretical experimental analysis can be applied match their energy levels; however, individual applications are hindered by several defects, such as poor visible-light utilization efficiency. The combination of benefit from virtues both while avoiding drawbacks them. Notably, with high specific surface area long-range ordered structure ensure a uniform distribution POMs, which cannot only prevent self-aggregation but also allow exposure more active sites for catalysis. POM@MOF identified promising materials photocatalysis because diverse unique advantages, ultrahigh porosity, large area, excellent electron redox transformation. work, we present an overview developments composite-based catalysts visible light induced strategies employed preparation summarized discussed particular focus on stability materials. representative works photocatalytic water splitting, CO2 reduction, degradation pollutants, selective oxidation organics highlighted. Special is paid synergistic effects MOF POM that result enhanced performance. Besides, reusability these discussed. Also, unsolved problems development opportunities field proposed.

Metal-organic frameworks (MOFs) have been widely recognized as one of the most fascinating classes materials from science and engineering perspectives, benefiting their high porosity well-defined tailored structures components at atomic level. Although intrinsic micropores endow size-selective capability surface area, etc., narrow pores limit applications toward diffusion-control large-size species involved processes. In recent years, construction hierarchically porous MOFs (HP-MOFs), MOF-based composites, derivatives has captured widespread interest to extend conventional materials. this Review, advances in design, synthesis, functional are summarized. Their structural characters various applications, including catalysis, gas storage separation, air filtration, sewage treatment, sensing energy storage, demonstrated with typical reports. The comparison HP-MOFs traditional (e.g., zeolite, silica, carbons, metal oxides, polymers), subsisting challenges, well future directions research field, also indicated.
