The (photo)electrochemical oxidation of benzyl alcohol and its derivatives serves as an important model system, not only because benzyl alcohol oxidation is a critical industrial process, but also because it offers valuable insights into electrocatalytic biomass conversion. Tailoring this reaction through electrochemical and photoelectrochemical methods using heterogeneous noble and transition metal electrocatalysts presents a green approach and the potential for uncovering new reaction mechanisms. This review article positions the electrochemical oxidation of benzyl alcohol as an alternative to the OER to produce H<small><sub>2</sub></small>, highlighting recent mechanistic studies involving noble and transition metal electrocatalysts. Furthermore, we discuss the electronic substituent effects on this reaction, which have been well-explored in organic oxidation pathways but remain underexplored in (photo)electrocatalytic contexts.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"2 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031402","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}
