“…Furthermore, in addition to its excellent ORR activity, it also has exceptional performance in the HER and OER catalytic processes. [140][141][142] Xu et al [143] reported the embedding of a single cobalt atom in a sandwich-like multimodally porous N-doped dualcarbon architecture to achieve fast electron transfer, accelerated oxygen/electrolyte diffusion, and timely water removal by exploiting the abundant Co-N 4 active centers of the catalyst and the optimized multimodal pore structure with a half-wave potential of 0.72 V, comparable with commercial Pt/C. Aside from the single ORR catalytic activity, Doan et al [136] designed cobalt single atoms (CoSAs)-MoS 2 nanosheets grown vertically on 3D TiN nanorod arrays.…”

Electrocatalysis, which involves oxidation and reduction reactions with direct electron transfer, is essential for a variety of clean energy conversion devices. Currently, the vast majority of studies regarding electrocatalysis reactions focus on strong acidic or alkaline media because of the higher catalytic activity. Nevertheless, some inherent drawbacks, including the corrosive environment, expensive proton exchange membranes, and side effects, are still hard to break through. A sustainably promising way to overcome these shortcomings is to deploy neutral/near‐neutral electrolytes for electrocatalysis reactions. Unfortunately, insufficient research in this area due to the lack of attention to related issues has slowed down the development process. In this review, we systematically review the catalytic reaction mechanisms, neutral electrolytes, electrocatalysts, and modification strategies carried out in neutral media on the three most common electrocatalytic reactions, that is, hydrogen evolution reaction, oxygen reduction reaction, and oxygen evolution reaction. Furthermore, the advanced characterization tools for guiding catalyst synthesis and mechanistic studies are also summarized. Eventually, we propose some challenges and perspectives on electrocatalysis reactions in neutral media and hope it will attract more research interest and provide guidance in neutral electrocatalysis.

Precious metals are effective catalysts for the hydrogen evolution reaction, but their high cost with complicated operation steps drives people to search for non–noble‐metal alternatives. Building rational design concept for efficient electrocatalyst relies on the capability to control the structure and composition. Herein, a Ni/Cu bimetallic mesoporous MOFs with 4,4′,4″‐(1,3,5‐triazine‐2,4,6‐triyl)tribenzoic acid as the robust ligand has been assembled via a one‐step solvothermal method. Due to the extensive conjugate plane and high nitrogen content, the catalyst possesses large pore size of 17 nm and fast electron transfer rate, which favors hydrogen bubble overflow and exposes more active sites to solid–liquid interfaces. The bimetallic interaction between highly conductive Cu ions and Ni ions allows it to improve charge migration and realize excellent conductivity. The functionalized electrode requires an overpotential of 132 mV to achieve 10 mA current density with a small Tafel slope (87.7 mV·dec−1) and continuous electrolysis for 24 h.
