Single-atom catalysts (SACs) demonstrate great promise for enabling efficient alkaline HER catalysis at maximum atom utilization efficiency. In this review, we provide a comprehensive overview of the recent progress in SACs for the HER application in alkaline environments. The fundamentals of alkaline HER are first introduced, followed by a justification of the need to develop SACs. The rational design of the SACs including the inherent element property, coordination environment, SAC morphology, and SAC mass loading are highlighted. To facilitate the development of SACs for alkaline HER, we further propose the remaining challenges and perspectives in this research field.</p></div>","PeriodicalId":61638,"journal":{"name":"材料导报:能源(英文)","volume":"2 3","pages":"Article 100144"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666935822000829/pdfft?md5=7c10df61682faf80c2dccb16282b55f1&pid=1-s2.0-S2666935822000829-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45675684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal stability, electronic properties, and catalytic activities of the metal center can be controlled via manipulating the neighboring heteroatoms such as nitrogen, oxygen, and sulfur. Due to the atomical dispersion of the active catalytic centers, the amount of metal required for catalysis can be decreased. Furthermore, new possibilities are offered to easily control the selectivity of a given transformation process as well as to improve turnover frequencies and turnover numbers of target reactions. Among them, Fe–N–C single atom catalysts own special electronic structure, and have been widely used in many fields of electrocatalysis. This review aims to summarize the synthesis of Fe–N–C based on anchoring individual iron atoms on carbon/graphene. The spin-related properties of Fe–N–C catalysts are described, including the relation between spin and electron structure of Fe–N_<em>x</em> as well as the coupling between electronic structure of Fe–N_<em>x</em> and electronic (orbit) of CO₂, N₂ and O₂.

Herein, we reported a copper-indium-organic-framework (CuIn-MOF) based high-performance catalyst for eCO₂R. Electrochemical measurement results reveal that CuIn-MOF exhibits high Faradaic efficiency (<em>FE</em>) of CO and formate (300 mV, <em>FE</em>_CO = 78.6% at −0.86 V vs. RHE, <em>FE</em>_HCOO⁻ = 48.4% at −1.16 V vs. RHE, respectively) in a broad range of current density (20.1–88.4 mA cm⁻²) with long-term stability (6 h) for eCO₂R in 0.5 M KHCO₃ electrolyte solution. Specifically, through anion-regulation engineering, SO₄²⁻ anion precursor is more beneficial for the formic acid generation than NO₃⁻ anion precursor; while for SO₄²⁻ anion precursor, Cu plays a positive regulating role in eCO₂R to CO compared to In.
