Abstract Single‐atom (SA) cocatalysts (SACs) have garnered significant attention in photocatalysis due to their unique electronic properties and high atom utilization efficiency. This review provides an overview of the concept principles SA cocatalyst photocatalysis, emphasizing intrinsic differences SAs used classic chemical catalysis. Key factors that influence efficiency photocatalytic reactions, particularly hydrogen (H 2 ) production, are highlighted. further covers synthesis methods, stabilization strategies, characterization techniques for common photocatalysis. Notably, “reactive deposition” method, which often shows a self‐homing effect thus achieves maximum cocatalysts, is emphasized. Furthermore, applications various processes, including H evolution, carbon dioxide reduction, nitrogen fixation, organic synthesis, comprehensively reviewed, along with insights into artifacts these applications. concludes by addressing challenges faced SACs offering perspectives on future developments, aim informing advancing research energy conversion.

The practical application of electrocatalytic CO2 reduction requires adaptation to the fluctuating voltage output photovoltaic systems. However, potential-induced in-situ reconstruction catalyst complicates control and leads Faradaic efficiency (FE) instability across potential window. Here, we present a redox graphene-supported indium oxide (G-InOx), where rGO effectively regulates surface evolution InOx from In3+ In0 during reactions. multivalent In generated via lowers energy barriers for *OCHO formation dissociation, enhancing formate production. also environment, optimizing proton delivery active sites. Over wide range (−0.86 −1.37 V vs RHE), G-InOx achieves FEformate nearly 100%. This work offers straightforward efficient strategy scalable, high-performance electroreduction.

Abstract The rechargeable Zn‐redox battery represents a promising, efficient, and sustainable energy storage technology. Herein, novel 4‐nitrobenzyl alcohol (4‐NBA)‐assisted battery, driven by NiSe─Cu 2 Se/NF bifunctional electrocatalysts is developed. different redox activities of ─NO ─OH groups in 4‐NBA allow conversion for chemical production during the whole discharge/charge process, maximizing economic value technologies. Detailed charge analyses indicate that internal electric field within Se heterostructure modulates d‐band center, optimizes adsorption/desorption strength intermediates, reduces reaction barriers 4‐NBA. This electrocatalyst enables selective to 4‐aminobenzyl discharge process 4‐nitrobenzoic acid with Faradaic efficiencies above 96%. Consequently, 4‐NBA‐assisted achieves high power density 16.13 mW cm −2 maintains stable yield rate 15.92 µmol h −1 22.84 acid. work presents an appealing strategy integrating the‐whole‐process production, paving way developing multifunctional systems.
