Developing efficient methods for electrochemical energy conversion presents a promising solution to address these pressing issues. In the past few years, various electrocatalytic reduction reactions such as the hydrogen evolution reaction (HER), oxygen reduction reaction (ORR), nitrogen reduction reaction (NRR), nitrate reduction reaction (NO<small>₃</small><small>⁻</small>RR), and carbon dioxide reduction reaction (CO<small>₂</small>RR) have been investigated to create a pollution free green society and environment. Zn-based materials have garnered significant attention as potential candidates in the electrocatalytic reduction reactions owing to their precisely tuned structural and electronic properties, three-dimensional architectures, large surface areas, abundant active sites, high stability, and enhanced mass transport and diffusion capabilities. Numerous studies have been published investigating the potential of Zn-based materials in various electrocatalytic reduction reactions. However, there is a lack of comprehensive reviews systematically exploring the use of Zn-based materials in electrocatalytic reduction reactions. This review explores the structure–property–performance correlations of zinc-based catalysts, emphasizing their role in various electrocatalytic reduction reactions. We discuss the influence of structural modifications, such as doping, alloying, heterostructure formation, and morphological control, on the catalytic activity, stability, and selectivity of these materials. Special focus is given to the electronic structure modulation, active site optimization, and charge transfer mechanisms that underpin their performance. Recent advancements in synthesis techniques and characterization methods are highlighted to illustrate how tailored design strategies enhance catalytic efficiency. By presenting a comprehensive overview of zinc-based catalysts, this review aims to provide insights into their structure–performance relationships and offer guidance for the rational design of next-generation electrocatalysts for sustainable energy and chemical production.</p>","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 15","pages":" 2287-2321"},"PeriodicalIF":6.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144671317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, there are very few SF materials with high efficiencies, high stability and relatively high triplet state energy simultaneously. Diketopyrrolopyrroles (DPPs) have been found to achieve highly efficient intermolecular SF; however, they have not yet achieved efficient intramolecular SF (iSF). Herein, a series of covalently linked DPP oligomers (<em>E</em>(T<small>₁</small>) = ∼1.1 eV) were synthesized, and their iSF properties were investigated <em>via</em> time-resolved ultrafast fluorescence/absorption spectroscopy. The absorption spectra of oligomers changed significantly compared to their corresponding monomers, suggesting the presence of strong inter-chromophore electronic coupling in these oligomers. Meanwhile, the fluorescence quantum yield of these oligomers also dropped a lot, especially in polar solvents. Transient absorption spectra revealed that these oligomers could conduct iSF in polar solvents, but not in non-polar solvents. This, together with the large dropped fluorescence quantum yield in polar solvents, suggests that iSF in these oligomers was mediated by the charge-transfer state. More importantly, the SF rate and efficiency increase gradually from dimer (∼3.71 ns and ∼45.3%) to trimer (∼1.62 ns and ∼66.8%) and then to tetramer (∼1.08 ns and ∼85.3%). This may be caused by the larger diffusion space for the separation of the triplet state provided by the increasing number of DPP units in trimers and tetramers. The 85% iSF yield of tetramers is the highest recorded for DPP derivatives in solution. This work opens a new avenue for the design of novel efficient iSF materials based on DPP derivatives.</p>","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 15","pages":" 2417-2431"},"PeriodicalIF":6.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144671301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
