Enhancing extracellular electron transfer (EET) between microorganisms and electrodes in these systems is a rapidly evolving field. This Review presents recent and emerging advances in the development of novel electrode materials, including incorporation of conductive polymers (CPs), common nanomaterials, MXenes, and metal–organic frameworks (MOFs) to increase the conductivity and surface area available for microbial electrochemical reactions. We also discuss electrodes of the future, focusing on computational rational design and approaches that consider the microorganisms’ perspective in the design process. These include patterning to achieve biologically relevant surface architecture and mimicking the extracellular matrix to form artificial biofilms.","PeriodicalId":48544,"journal":{"name":"Trends in Chemistry","volume":"96 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139951530","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}

With low recycling rates worldwide, plastics upcycling is emerging as a promising alternative by using these abundant waste products as chemical feedstock for the production of materials and essential chemicals of higher economic value. However, the saturated C–C polymer backbones of polymers constituting ~60% of all plastic waste are unreactive and challenging to upcycle, often necessitating energy-intensive processes. This review examines state-of-the-art sustainable approaches employing the Principles of Green Chemistry to functionalize or cleave these unreactive polymer backbones, including alternative solvents, Earth-abundant metal catalysis, emerging low-energy approaches, and biocatalysis. Such sustainable strategies will enhance the attractiveness and practical feasibility of plastics upcycling to achieve a circular materials economy.</p>","PeriodicalId":48544,"journal":{"name":"Trends in Chemistry","volume":"38 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139758908","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}
