Oxidation State and Heterointerface Co‐Engineered Carrier Dynamics in POM@MOF Systems for Enhanced Photocatalytic Performance

ABSTRACT Optimizing carrier dynamics to elevate photocatalytic efficiency represents a central goal in the design of photocatalysts; however, achieving this remains a daunting challenge within the research community. In this study, we have devised and synthesized four types of intramolecular heterojunctions (POM@MOFs), constructed by integrating polyoxometalates (POMs) with metal–organic frameworks (MOFs). Specifically, we utilized an organic linker featuring a photosensitive phenothiazine core
