On one hand, machine learning has significantly accelerated the development of atomically dispersed metal-nitrogen-carbon (M-N-C) electrocatalysts, which traditionally heavily relied on heuristic approaches. On the other hand, the primary challenge of leveraging machine learning to expedite M-N-C materials discovery lies in the cost associated with data collection. We review recent machine learning integration strategies for M-N-C catalyst development, including discussions on the typical algorithms such as symbolic regression and convolutional neural networks employed for the theoretical design, synthesis optimization via active learning, and advanced microscopy characterization. Subsequently, we provide our perspective on potential near-future directions for furthering machine learning-assisted development of new M-N-C catalysts and elucidating the complex physicochemical mechanisms governing the selectivity, activity, and durability in this class of materials.</p></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"48 ","pages":"Article 101578"},"PeriodicalIF":7.9,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A particular advantage of electroanalysis is that the sensors may be incorporated directly into photocatalytic reactors to allow real-time <em>in situ</em> analysis. This can then facilitate more accurate process control in the photocatalytic reactor. This report highlights the use of electroanalysis to monitor photocatalytic processes, considering applications where it has been used to date. Relevant properties of the sensors, with particular interest on sensitivity and response times are detailed alongside comparison to the more commonly used analytical techniques. It also explores the most recent progressions beyond monitoring photocatalytic remediation processes including photocatalytic valorization and reactive oxygen species monitoring.</p></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"47 ","pages":"Article 101570"},"PeriodicalIF":7.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2451910324001315/pdfft?md5=bb9fcdad05edbaf96150a6a478d57d99&pid=1-s2.0-S2451910324001315-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous studies have predominantly focused on evaluating specific catalyst materials within various classifications and their preparation methods, but without addressing roles of supports. This review focuses on substrate considerations, performance evaluations, and prospectives. It provides a deeper understanding of the various strategies employed for in-situ growth of electrocatalysts and emphasizes the importance of different conductive substrates with case studies on the factors that affect catalytic activity. Furthermore, the prospects and challenges towards practical applications under some challenging conditions are highlighted. This review provides valuable strategies for the further development of rational design of catalyst–substrate as an enabling electrode.</p></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"47 ","pages":"Article 101566"},"PeriodicalIF":7.9,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2451910324001273/pdfft?md5=ee43d3018dce7f2b6528cf13ffa6633f&pid=1-s2.0-S2451910324001273-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141637561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
