The optimized Gr@Cu0.8 catalyst achieved a Faradaic efficiency of ~55% for ethylene (C2H4) at −0.87 V versus RHE. Density functional theory calculations reveal that interfacial charge transfer at the Gr@Cu interface lowers the energy barriers for both the CO2 activation and *CO dimerization, thus promoting the key C─C coupling step. Frontier orbital and d-band center analyses further demonstrate that the heterostructure elevates the Cu d-band center and improves orbital coupling with reaction intermediates, facilitating electron transfer and intermediate adsorption.

However, their development remains impeded primarily by the incompatibility between Mg anodes and conventional electrolytes. Herein, we report a novel multicomponent, high-concentration aqueous magnesium electrolyte design, realized by introducing isopropanol (IPA) and glucose (Glu) into a saturated MgCl2 solution, denoted as SMIG. The incorporation of IPA and Glu disrupts the original hydrogen-bond network of the SM electrolyte, reducing the content of free water and thereby mitigating water-related side reactions. This synergistic effect alleviates the corrosion of the Mg alloy anode and inhibits the hydrogen evolution reaction (HER) during magnesium deposition. As a result, the assembled polyaniline//Mg alloy aqueous MIB (AMIB) delivers a high specific capacity of 127.9 mAh g−1 at a current density of 0.2 A g−1 and retains 92.9% of its initial capacity after 300 cycles, with a Coulombic efficiency approaching 100%.

Alumina (Al2O3) is an irreducible oxide and an excellent support material in industrial catalysts because of its exceptional thermal stability, structural versatility, and affinity for metal anchoring and molecule adsorption. Isolated metal atoms having unique electronic structure enable 100% atom utilization efficiency and represent the cornerstone of single atom catalysts (SACs). Although the concept of SACs has advanced drastically, SACs on Al2O3 supports remain a relatively nascent area of research. This review systematically examines the landscape of SACs supported on Al2O3, assessing the synthetic strategies employed, expounding their structural characteristics, metal–support interactions, and applications. Commencing with an overview of the various transitional phases of Al2O3, we explore the critical role of surface defects and penta-coordinated Al3+ sites in coordinating and stabilizing metal atoms. Furthermore, we correlate these structural features to their catalytic performance, elucidated through advanced characterization techniques such as X-ray absorption spectroscopy and atomic-resolution electron microscopy. Through a comprehensive discussion, the review attempts to provide a clear and systematic explanation of the current accomplishments, obstacles, and future prospects in the emerging research field of single-atom catalysis.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 18","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148975056","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}

Hence, materials exhibiting structural evolution and consequent activity enhancement under cathodic potentials are highly desirable as tunable platforms for developing efficient HER electrocatalysts. Herein, for the first time, we unravel β-Co(OH)2 as a prolonged activation-enabled phase that evolves under cathodic potential. Strategically employing Co3(PO4)2 as an alkaline-responsive precursor for β-Co(OH)2 and activating through a steady-state technique generated an efficient electrocatalyst that attained −10 mA/cm2 at 114 ± 8 mV, which is ~156 mV less than its preconditioned analog. Comparative electrocatalytic analysis of Co3(PO4) 2-derived β-Co(OH)2 against its conventional counterpart unveils the governing influence of the phosphate precursor in enhancing the time-dependent performance boost. The OER activity of the material was rationally tuned by heterostructure engineering of Co3(PO4)2 with Ag3PO4 via a room-temperature route. The evolved active phase, CoOOH/Ag2O, attained 10 mA/cm2 at 240 mV overpotential, surpassing the individual counterparts. The material exhibited a Faradaic efficiency of 97 ± 2% following the PDET mechanism. The ~100 h durability of electrode materials, coupled with their efficient performance in overall water splitting (10 mA/cm2 at 1.65 V, 75 h stability), underscores their practical viability.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 18","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148975122","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}

Herein, hydroxypropyl trimethyl ammonium chloride chitosan (HTCC), a quaternized biomass derivative, is developed as a cationic binder that fundamentally suppresses the polyiodide shuttle effect. Unlike binders with weak hydrogen bonding that can only immobilize I3−, HTCC immobilizes both I3− and I5− through strong electrostatic interactions, complemented by hydrogen-bonding interactions. The optimized aqueous AZIBs exhibit exceptional antiself-discharge performance, as demonstrated by a stable open-circuit voltage of 1.322 V and a Coulombic efficiency above 96.2% after a 72 h rest. Furthermore, they deliver a highly specific capacity of 216.4 mAh g−1 at 0.1 A g−1 and outstanding long-term cycling stability, retaining 90.1% of their initial capacity after nearly 40,000 cycles at 5.0 A g−1.

Herein, we report a time-controlled selective decalcification strategy to reconstruct dense CaMnO3 perovskite into Mn-rich porous oxides for NO oxidation. Acid etching progressively removed Ca from the CaOMn framework, forming MnO2-like porous structures with well-defined [MnO6] units and MnOMn bridges. The optimized catalyst, denoted as CMO-24 h, decreased the temperature required for 50% NO conversion from 378 to 181 °C and increased the maximum NO conversion from 54% to 92%. The promoted activity arose from an optimized MnOMn lattice-oxygen microenvironment within the reconstructed porous framework. Mn enrichment and pore formation increased the accessibility of Mn-rich surface domains, while the connected MnOMn network facilitated Mn redox cycling among Mn2+/Mn3+/Mn4+ at low temperatures. Meanwhile, enriched surface-accessible lattice oxygen and an expanded surface/subsurface lattice-oxygen reservoir provided reactive oxygen for the oxidation of adsorbed NO-derived species. Temperature-programed desorption and in situ diffuse reflectance infrared Fourier transform spectroscopy (with NO or NO + O2 as probes) further revealed that CMO-24 h enhanced NOx adsorption/desorption and accelerated the evolution of nitrosyl/nitrite-type species toward nitrate- and NO2-related species.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 18","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148965729","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}

According to their compositional characteristics, MOF-derived materials can generally be classified into three categories: MOF-derived carbon materials, MOF-derived metal compounds, and MOF-derived metal/carbon composites. This review covers representative studies published from 2014 to 2026 across these three material categories. This review systematically summarizes recent research progress on these three classes of MOF-derived materials in lithium-ion batteries (LIBs), zinc-ion batteries (ZIBs), and supercapacitors, with a focus on their preparation strategies, structure–property relationships, and mechanisms for enhancing electrochemical performance. Finally, the current challenges and future development directions of MOF-derived materials in electrochemical energy storage are discussed.
