Amid the intensifying global energy crisis, the development of renewable pathways for green hydrogen production has become imperative. Numerous materials have been investigated as electrocatalysts for water splitting and fuel cell technologies, with molybdenum disulphide (MoS2) emerging as a particularly promising candidate owing to its versatility in major aqueous electrochemical processes. This review provides an integrated perspective on recent advances in MoS2 as a multifunctional electrocatalyst for hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction and hydrogen oxidation reaction, the key half-reactions that govern water splitting and fuel cell systems. The kinetics of these reactions, governed by the Sabatier principle, can be optimised through careful control of proton-coupled electron transfer pathways. MoS2 has attracted significant attention not only as a non-noble catalyst but also as a robust support for constructing highly active catalytic systems. Its layered framework, tuneable electronic structure and inherent defect sites provide a versatile platform that can be engineered into efficient catalytic systems, enhancing reaction kinetics, intermediate binding and overall activity. This review examines and compares the activity of MoS2-based catalysts and summarises recent progress and challenges in their development as electrocatalysts for water-related energy applications.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 6","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13000686/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147479227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report how ethylene glycol (EG) addition can maximize BHET formation using leading PET hydrolases, LCCICCG, and PHL7. EG at any level above 2–5% vol/vol was found to decrease the steady-state enzymatic degradation rates while enhancing the relative production of BHET. For LCCICCG, the highest measured BHET levels (product fraction approaching 0.5) were attained at EG levels of ∼27–29% and reaction temperature ∼62.5°C. EG shortened the enzymatic reaction lag-phase and lowered the lag-phase increase with PET crystallinity. EG works by perturbing the adsorption, including nonproductive adsorption, of the enzymes to the PET surface, which manifests as an apparent change in substrate affinity (increases the invKm in interfacial kinetics modeling) and directs the enzyme more to the liquid phase.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 6","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13000671/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147479236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, high-areal-capacity cathodes are fundamentally hindered by multiscale limitations, including microscopic issues associated with the chemo-mechanical properties of conventional binders and macroscopic constraints arising from increased tortuosity in thick electrodes. This review article explores two representative approaches to realizing high-areal-capacity cathodes. The review begins with a quantitative analysis illustrating how an increase in electrode thickness results in improved energy density. The subsequent section outlines the analytical methodologies used to diagnose the key limitations of high-areal-capacity electrodes and to verify the effectiveness of strategies developed to overcome these challenges. Building on these analytical insights, the following section discusses the critical properties required of polymer binders to address these technical issues, followed by practical examples that demonstrate successful binder designs. The review then introduces electrode architectural engineering strategies, highlighting how continuous and durable pathways can be constructed within electrodes to enhance both ionic/electronic conductivity, as well as overall structural integrity. Overall, this discussion provides a comprehensive design perspective that bridges material-level and structural-level considerations, offering general guidelines for the development of practical high-energy-density batteries enabled by high-areal-capacity electrode technology.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 6","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147466472","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}

However, its conventional production through the energy-intensive Haber–Bosch process results in significant carbon dioxide emissions. Here, we report an eco-friendly solid-state synthesis of bismuth vanadium oxide supported on treated carbon black (Bi4V6O21@CB), denoted as BV64@CB, as an efficient electrocatalyst for the nitrogen reduction reaction (NRR). This electrocatalyst exhibits exceptional activity owing to its unique coordination environment, which effectively sustains electron deficiencies. In this system, vanadium (V5+) active sites facilitate nitrogen (N2) adsorption, while bismuth (Bi3+) promotes the hydrogenation of adsorbed N2, leading to the formation of *NNH intermediates on the BV64@CB surface. The cooperation between vanadium and bismuth enhances NRR efficiency, thereby promoting NH3 synthesis via the distal associative pathway. These mechanistic insights are supported by in situ X-ray absorption spectroscopy and Raman analyses. The BV64@CB electrocatalyst exhibits an impressive average NH3 yield rate of 370.1 μg h−1 mgcat−1 and a Faradaic efficiency of 90.94% at −0.4 V versus the reversible hydrogen electrode in a 0.2 M Li2SO4 electrolyte (pH 5).

In this work, we report the development of a bio-organocatalytic cascade, combining stereoselective transamination catalyzed by ω-transaminases (ω-TAs) in neat organic solvent and choline chloride (ChCl)-mediated direct amidation. This strategy enables the synthesis of chiral amides from prochiral carbonyl compounds and carboxylic acids under solvent-free microwave conditions. After optimizing the biocatalytic transamination in MTBE, we applied the method to the synthesis of key intermediates of Racecadotril and AVR-48, achieving full conversions and enantiomeric excess above 99%. The amidation step, promoted by ChCl without traditional activating agents, proved highly efficient for a wide range of aliphatic and aromatic carboxylic acids, affording the target amides in 60%–86% yields. Solvent evaporation after the transamination step was essential to remove interfering byproducts such as acetone, thus improving amidation yields. Overall, this integrated methodology provides a green, efficient, and scalable route to access amide-based building blocks in high optical purity, opening new avenues for sustainable pharmaceutical manufacturing.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 6","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12989220/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147462355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, stable radicals, lacking intrinsic conductivity, are utilized as redox-active materials. A recently introduced strategy to overcome this shortcoming is to incorporate stable radicals, i.e., (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO), into a polythiophene backbone. Thereby, an electrode material was obtained which does not require conductive additives. The current computational study aims to elucidate the functionality of this material by drawing in-depth structure–property relationships utilizing a hierarchical molecular and quantum mechanical approach. Initially, structural properties of the electrode material's macroenvironment—containing the functionalized polythiophene, electrolyte, and solvent—were assessed in various charging states by molecular dynamics simulations. Subsequently, electronic properties were investigated by time-dependent density functional theory for 564 microenvironments. Via this computational setup, the electronic communication within the material was assessed along intrastrand and interstrand CT processes involving the respective TEMPO and polythiophene units. Thereby, our hierarchical computational approach reveals that the intrinsic conductivity and charge storage capacity of the electrode material stems from efficient intrastrand TEMPO-polythiophene CT processes along short and rigid amid linkers. These insights help to tailor improved conductive organic electrode materials with higher charging and discharging rate capabilities.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 6","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12989221/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147462376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
