However, existing catalysts suffer from rapid deactivation due to the inevitable overoxidation. Herein, we present an amorphous phosphorus-doped CoFe₂O₄ catalyst that achieves industrial-level current densities (1 A cm⁻²) at ultralow potentials (0.06, 0.65, and −0.17 V vs. reversible hydrogen electrode) for hydrazine, sulfion, and borohydride electrooxidation, respectively, along with 400-hour stability at 300 mA cm⁻² in a hydrazine-assisted electrolyzer. Mechanistic studies reveal electron transfer from Co-P ligands to Co-O ligands, which enhances the involvement of Co-O ligands in low-potential electrooxidation while protecting Co-P ligands from overoxidation. Furthermore, more positive charges on Co centers lower the activation barrier for such pollutant electrooxidation. This work opens a paradigm for designing robust electrocatalysts by decoupling catalytic activity from oxidative deactivation.</p>","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"27 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep learning approaches are becoming cost-effective alternatives to high-throughput experimental methods for ligand identification. Here, to predict the binding affinity between proteins and small molecules, we introduce Ligand-Transformer, a deep learning method based on the transformer architecture. Ligand-Transformer implements a sequence-based approach, where the inputs are the amino acid sequence of the target protein and the topology of the small molecule to enable the prediction of the conformational space explored by the complex between the two. We apply Ligand-Transformer to screen and validate experimentally inhibitors targeting the mutant EGFR<sup>LTC</sup> kinase, identifying compounds with low nanomolar potency. We then use this approach to predict the conformational population shifts induced by known ABL kinase inhibitors, showing that sequence-based predictions enable the characterisation of the population shift upon binding. Overall, our results illustrate the potential of Ligand-Transformer to accurately predict the interactions of small molecules with proteins, including the binding affinity and the changes in the free energy landscapes upon binding, thus uncovering molecular mechanisms and facilitating the initial steps in drug design.</p>","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"129 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
