Magnetic separation of photocatalysts holds great promise for water treatment. A magnetic separation method has a positive effect on the recovery of catalysts after degradation. In this paper, an efficient and reusable catalytic system is developed based on coating magnetic Fe3O4 by depositing Fe2+ on the surface of ZnO. The Fe3O4/ZnO nanocomposite exhibits enhanced performance for organic pollutant degradation. The Fe3O4/ZnO system demonstrates a high photocatalytic activity of 100% degradation efficiency in Rhodamine B (RhB) degradation under UV light irradiation for 50 min. The excellent photocatalytic activity is primarily due to the separation of photogenerated electron-hole pairs being facilitated by the strong interaction between Fe3O4 and ZnO. The induction of the magnetic Fe3O4 endows the Fe3O4/ZnO composite with superior magnetic separation capability from water. Experiments with different radical scavengers revealed that the hydroxyl radical (·OH) is the key reactive radical for the effective degradation of RhB. This work innovatively affords a common interfacial dopant deposition strategy for catalytic application in the degradation of organic dye pollutants and catalyst separation from wastewater efficiently.

Photocatalysis represents a solar‐to‐chemical energy transformation process including three processes, light absorption, charge separation/transfer, and surface reactions. Owing to the merits of single‐atom catalysts (SACs) toward maximal atom utilization, unsaturated coordination structure, and tunable electronic configuration, single‐atom photocatalysts (SAPs) exhibit extraordinary photocatalytic performance toward a series of sustainable reactions. Accompanied by the complexity of photocatalytic processes and the realistic demand for tandem reactions as well as the promotion of intricate reactions with multiple reaction routes and intermediates, significant efforts are desired to gain in‐depth insights into the design and fabrication of synergistic photocatalysts. In this review, the first part discusses the design principles from traditional semiconductor‐based photocatalysts to SAPs. Moreover, six basic models of synergistic photocatalysts including remote dual atoms, bridged dual atoms, adjacent dual atoms, single atoms + clusters/nanoparticles (NPs), single atoms + defects, NPs + NPs, are highlighted and distinguished by their structure features. Second, specific examples of SAPs and synergistic photocatalysts are appreciated under the category of CO2 reduction reaction (CO2RR), hydrogen evolution reaction (HER), nitrogen reduction reaction (NRR), and pollutants degradation. Finally, this review will conclude by discussing the challenges and future perspectives of SAPs and synergistic photocatalysts for sustainable applications.
