The development of logical visible-light-driven heterogeneous photosystems for water splitting is a subject of new research. As the first example of a noble-metal-free photocatalyst for both H and O production, a high-nuclear {Cu (μ -Cl) (μ -Cl) }-based polyoxometalate (POM)@metal-organic framework (MOF) (ZZULI-1) is rationally designed to serve as a robust dual-functionalized photocatalyst. ZZULI-1 exhibits highly efficient photocatalytic H evolution (6614 μmol g h ) and O evolution (1032 μmol g calculated for the first 6 min). The {Cu (μ -Cl) (μ -Cl) } clusters and mixed POMs not only work as the active units for H and O production, respectively, but also improve the effective electron transfer between the photosensitizer and ZZULI-1. The highly stable dual-functionalized ZZULI-1 affords new penetrations into the development of cost-effective high-nuclear cluster-based POM@MOFs for efficient solar-to-fuel generation.
