However, the principle for QD selection for photocatalysis remains debated. A critical question emerges against the background that near-unity photoluminescence quantum yield (PLQY) QDs become commonly available: Should QD photocatalysts prioritize high-PLQY QDs or low-PLQY ones to maximize catalytic performance? To address this question, CdSe-based QDs are selected as a model system, and the role of intrinsic defects of QDs is discussed, which serve as the direct linkage between PLQY and photocatalytic performance of QDs. Defect states are known to quench PLQY, while their effects on photocatalysis-either promoting or suppressing-are both widely reported. Representative studies on PLQY-related photocatalysis are then reviewed. This debate is finally resolved through mechanistic insights into defects, and it is proposed that ideal photocatalysts should be based on ideal light-emitters. For specific photocatalytic applications, initial PLQY should be paid attention and surface-engineering strategies should be applied to pristine defects-eliminated QDs.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2501100"},"PeriodicalIF":7.5,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144673488","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}

Current RAPs employed in AZIBs are primarily conjugated aromatic polymers or aliphatic polymers with CC bonds, which can potentially contribute to microplastic pollution at the end of the battery's life. In this work, natural cellulose is selected as the parent polymer and, through chemical grafting, introduced radical oligomers to afford cellulose-g-oligo(TEMPO) as electroactive materials for AZIBs. Chemical characterizations confirm the successful synthesis of targeted polymer electrode materials with a theoretical capacity of 100 mAh g-1. The electrochemical performance of the AZIBs demonstrates that the cell can deliver a voltage of 1.55 V, an initial capacity of 73 mAh g-1, and retains 88% of its capacity after 1000 cycles.

This review summarized the research progress of LSPR materials in photothermal catalytic RWGS reactions. First, the characteristics and mechanism of photothermal catalytic RWGS reactions are introduced. Then, the basic principles and characteristics of LSPR materials are displayed, including their LSPR effect and the resulting photothermal conversion ability. Furtherly, the recent development of LSPR materials for photothermal RWGS reactions were compared in terms of their reaction activity, selectivity, and reaction mechanism. Finally, the existing problems in current research were discussed, and future research directions were proposed.

Various catalysts are designed into the cathode to enhance the conversion efficiency of lithium polysulfides (LiPSs) and improve the comprehensive performance of LSB. Despite considerable attention devoted to discovering novel catalysts, catalyst passivation remains a frequently overlooked issue. This review summarizes recent findings on catalyst passivation mechanisms and coping strategies in LSBs. It also clarifies a common misconception in LSB catalyst design: that stronger catalyst-polysulfide interactions necessarily improve catalytic performance. A stronger interaction between these two components does not necessarily indicate superior catalytic performance and may actually lead to catalyst passivation. The catalyst passivation mechanisms are categorized into two types, based on the strength of the interaction between the catalyst and sulfur/sulfides. The first type involves a strong interaction, leading to physical coverage-induced reversible catalyst passivation. The second type is characterized by an ultra-strong interaction, resulting in chemical reaction-induced irreversible catalyst passivation. The coping strategies to guide the design of optimal catalyst for the cathode of LSB is also summarized. Finally, the future prospects and challenges of catalyst coping strategies in LSB are discussed.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2500810"},"PeriodicalIF":7.5,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641327","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}
