In photosynthesis, solar energy is harvested by photosensitizers, and then, the excited electrons transfer via a Z-Scheme mode to enzymatic catalytic centers trigger redox reactions. Herein, we constructed core-shell Z-scheme heterojunction of semiconductor@single-atom catalysts (SACs). The oxygen-vacancy-rich ZnO core single-atom Co-N4 sites supported on nitrogen-rich carbon shell (SA-Co-CN) act as photosensitizer enzyme-mimicking active centers, respectively. Driven built-in electric field across heterojunction, photoexcited could rapidly (2 ps) from n-type p-type SA-Co-CN shell, finally boosting performance surface-exposed for peroxymonosulfate (PMS) activation under light irradiation. synergies between photocatalysis heterogeneous Fenton-like reaction lead phenomenally enhanced production various reactive oxygen species rapid degradation microcontaminants in water. Experimental theoretical results validate that interfacial coupling with greatly facilitates PMS adsorption reducing enhancing cascade electron processes photo-Fenton-like reaction.

Abstract The efficiency of photocatalytic hydrogen evolution is currently limited by poor light adsorption, rapid recombination photogenerated carriers, and ineffective surface reaction rate. Although heterojunctions with innovative morphologies structures can strengthen built‐in electric fields maximize the separation charges. However, how to rational design novel multidimensional simultaneously improve above three bottleneck problems still a research imperative. Herein, unique Cu 2 O─S@graphene oxide (GO)@Zn 0.67 Cd 0.33 S Three dimensional (3D) hollow heterostructure designed synthesized, which greatly extends carrier lifetime effectively promotes H production rate reached 48.5 mmol g −1 h under visible after loading Ni 2+ on heterojunction surface, 97 times higher than that pure Zn nanospheres. Furthermore, reach 77.3 without cooling, verifying effectiveness photothermal effect. Meanwhile, in situ characterization density flooding theory calculations reveal efficient charge transfer at p‐n 3D interface. This study not only reveals detailed mechanism depth but also rationalizes construction superior heterojunctions, thus providing universal strategy for materials‐by‐design high‐performance heterojunctions.
