Here, we report a green and scalable molten-salt templating strategy using NaCl to construct a two-dimensional ultrathin mesoporous carbon-supported Pt catalyst (Pt SA-NC /2D-OMCN) via simple calcination and water washing. The catalyst integrates dual mesopores: small mesopores (~3.8 nm) increase active site density, while large mesopores (20-30 nm) enhance mass transport. Combined with nitrogen dopants and edge defects that anchor Pt species, this architecture ensures uniform dispersion and structural stability of Pt single atoms and clusters. Benefiting from this wellengineered dual-mesoporous catalytic networks, Pt SA-NC /2D-OMCN exhibits excellent ORR activity and long-term durability in both three-electrode systems and practical fuel cell tests. This work presents a scalable design strategy for constructing high-performance, low-Pt ORR catalysts, and broadens the application scope of atom-cluster coexisting systems in fuel cell electrocatalysis.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"90 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133522","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}

Despite their advantages, the commercialization of Li–S batteries is constrained by the poor electrical conductivity, polysulfides shuttle effects, and sluggish redox kinetics. Covalent triazine frameworks (CTFs), a class of porous organic polymers featuring high nitrogen content, extended π-conjugation, and excellent thermal and chemical stability, have recently emerged as versatile materials to address these issues. This review summarizes the working principles and major challenges of Li−S batteries, along with various synthesis approaches for CTFs. Recent progress in applying CTFs as sulfur host materials, cathodes, and separators in Li−S batteries is discussed, emphasizing their multifunctional roles in suppressing polysulfide shuttling, improving electron/ion transport, and enhancing cycling stability. Finally, the current limitations and future research directions for CTF-based materials in Li−S batteries are highlighted. The objective of this review is to offer valuable insights for the rational design of advanced CTFs and promote their application in next-generation high-performance energy storage technologies.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"10 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145127902","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}

Gopinath","doi":"10.1039/d5cc04056f","DOIUrl":"https://doi.org/10.1039/d5cc04056f","url":null,"abstract":"Photocatalytic water splitting is considered as one of the efficient methods for producing green hydrogen. However, the sluggish oxygen evolution reaction (OER) kinetics with four electrons limits the overall efficiency of water splitting. Biomass components/biomass derivatives are the renewable carbon feedstock and abundantly available in nature. It is prudent to make use of electrons and holes concurrently in photocatalysis for H2 production and oxidation of biomass components, respectively, due to latter’s occurrence at low potential (≤1 V) than OER (&gt;1.23 V), to value-added products (VAPs); this approach makes the entire process to be energy-efficient and kinetically superior. This potential approach could effectively utilize the charge carriers as well as abundant renewable resources of water and biomass simultaneously, thus meeting the sustainability, energy conversion and economic goals together. Parallel utilization of the charge carriers for redox reactions also enhances the sustainability of the catalyst system employed. Interestingly, biomass component oxidation to VAPs occur in several steps, which not only enhances holes utilization, but also provides an opportunity to design better catalyst to enhance selectivity of the targeted product. Carrying out such reactions under aerobic or anaerobic conditions, and different pH conditions offer to fine tune the product selectivity. Current review provides a detailed overview of the recent developments in this emerging area with three different types of photocatalyst systems, such as oxide, chalcogenide, carbon-based materials. Among them, the oxide-based system demonstrated the higher activity with sustainability, maintaining performance over 300 h. While many of these systems exhibited high selectivity towards a single product, 100 % selectivity to lactic acid from glycerol was observed with BiVO4 integrated TiO2 catalyst. Finally, the challenges, opportunities and future perspectives in this thriving field is listed, and they underscore the role of carbon-neutral economy towards achieving a potentially sustainable future.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"3 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133531","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}
