Here, we develop a class of hybrid aqueous electrolytes with an organic-solvent-free primary solvation shell, favoring facile desolvation.

The enhanced hydrogen bonds between solvated CH<sub>3</sub>COO<sup>−</sup> and H<sub>2</sub>O hinder DMSO from replacing solvated H<sub>2</sub>O. This weak solvation structure facilitates fast charge transfer kinetics and rapid Zn<sup>2+</sup> flow through gradient solid electrolyte interphase. At −20°C, stable plating/stripping (5,600 h) and high Zn utilization (51%) are achieved. Furthermore, polyaniline||Zn batteries manifest low polarization (0.05 V), long cycling (8,800 cycles), and high rate. Importantly, this design strategy is generally extended to other hybrid electrolyte systems.

The integration of intracellular biochemical pathways with semiconductor materials offers superior product selectivity and efficient light utilization in solar-driven biocatalysis. However, the complicated multidisciplinary features and limited understanding of extracellular electron transfer at the biological-material interfaces hinder the practical application of biotic-abiotic hybrid systems for converting solar energy. In this perspective, we summarize the fundamental mechanisms of biohybrid systems for solar-to-chemical conversion and highlight ongoing challenges and promising directions for future development. First, a comprehensive overview of biotic-abiotic hybrid systems is introduced together with the mechanism of extracellular electron transfer for chemical production. Then, recent achievements of biohybrid systems for H<sub>2</sub> production, CO<sub>2</sub> reduction, N<sub>2</sub> fixation, and chemical synthesis are discussed in detail. Finally, the current challenges in biotic-abiotic hybrid systems and prospective research directions are explored.</div></div>","PeriodicalId":268,"journal":{"name":"Chem","volume":"11 2","pages":"Article 102351"},"PeriodicalIF":19.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These complexes typically absorb in the blue region of the electromagnetic spectrum. Here, we engineered an ERED to form CT complexes that absorb red light. Mechanistic studies indicate that red-light activity is due to the growth of a red-absorbing shoulder off the previously identified cyan absorption feature. Molecular dynamics simulations, docking, and excited-state calculations suggest that the cyan feature involves a π→π∗ transition on flavin, whereas the red-light absorption is a π→π∗ transition between flavin and the substrate. Differences in the electronic transition are due to changes in the substrate-binding conformation and allosteric tuning of the electronic structure of the cofactor-substrate complex. Microenvironment tuning of the CT complex for red-light activity is observed with other engineered photoenzymatic reactions, highlighting this effect’s generality.</div></div>","PeriodicalId":268,"journal":{"name":"Chem","volume":"11 2","pages":"Article 102318"},"PeriodicalIF":19.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142439790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A gasoline yield of up to 87% is achieved over a dual-catalyst system comprising WZr-KIT-6 and HZSM-5 at 240°C. The WZr-KIT-6 catalyst facilitated the activation and pre-cracking of PE chains into unsaturated oligomers over Si-O-Zr and W-O(H)-Zr sites. These unsaturated oligomers, characterized by increased mobility and reactivity, were subsequently converted into C<sub>4</sub>–C<sub>12</sub> gasoline-range compounds through β-scission, isomerization, and hydride transfer over HZSM-5. The synergistic reaction mechanism over mesoporous and microporous materials was crucial for enhancing the efficiency and selectivity of PE conversion.</div></div>","PeriodicalId":268,"journal":{"name":"Chem","volume":"11 2","pages":"Article 102340"},"PeriodicalIF":19.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142589051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
