![]() ![]() Owing to the stabilization of single-site Pd and Ir catalysts by MOFs framework as well as the proximity of them favoring fast electron transfer, UiO-67-Ir-PdX 2, under visible light, exhibits up to 25 times of Pd catalyst turnover number than the existing catalysis systems. ![]() Herein, we report a new strategy for addressing Pd reoxidation problem by the fabrication of spatially proximate Ir III photocatalyst and Pd II catalyst into metal-organic framework (MOF), affording MOFs based Pd/photoredox catalysts UiO-67-Ir-PdX 2 (X = OAc, TFA), which are systematically evaluated using three representative Pd-catalyzed oxidation reactions. Palladium catalyst turnover by reoxidation of a low-valent Pd species dominates the proceeding of an efficient oxidative transformation, but the state-of-the-art catalysis approaches still have great challenges from the perspectives of high efficiency, atom-economy and environmental-friendliness. ![]()
