The production of chemical energy using light resources is a charming and sustainable solution to energy and environmental problems. Extensive research is directed to further prolong the lifetime of charge carriers and to increase the rate of electron transfer for nano‐photoactive catalysts. Especially, spindependent electron‐hole recombination process has gained much attention. However, the direct effect of spin degree on photo‐catalysis performance is largely unexplored, which hinders the advancement of nano‐catalyst design. In order to address the above problems, Xue et al. (article No. 1700029 ) have designed a model catalyst system by combing Cu 2+ , carbon dots (CDs) and layered double hydroxides (LDHs). The results demonstrate: 1) the confined nanointerlayer of anisotropic LDHs provides Cu‐CDs with highly aligned dipoles and enhanced spin‐orbit coupling, which leads to the forbidden radiative recombination and prolonged exciton lifetime; 2) LDHs as nano‐reactors provide a confined microenvironment for catalysis reaction, which shortens the electron transfer pathway and reduces the exciton loss. Ultimately, these improvements contribute to the enhancement of photo‐catalysis performance for a model photo‐oxidation reaction of 1,4‐dihydro‐2,6‐dimethylpyridine‐3,5‐ dicarboxylateis (1,4‐DHP).
