While alkaline CO2 electrolyzers suffer from low CO2 utilization due to cathodic carbonate formation and crossover, acidic CO2 electrolyzers suffer from low CO faradaic efficiency. Reverse-bias Bipolar Membrane (BPM) cell architectures have been proposed to promote cathodic proton transport, yet resulted in limited cell lifetimes due to complex degradation and failure regimes. A thorough diagnosis of BPM cell dynamics is missing to date. Here, we build and diagnose an efficient zero-gap reverse-bias BPM CO2-to-CO electrolyzer cell deploying CO-selective single Ni atom cathode catalysts. We analyzed its key cell performance parameters and diagnosed the cell stability and failure regimes over 100 hours. The electrolyzer cell showed excellent performance up to 500 mA cm-2 with CO faradaic efficiency near 100 %. The proton-controlled ion transport in the cathode was directly confirmed by an experimental carbon cross-over coefficient (CCC) of zero, suggesting minimal carbon loss due to carbonate formation. This was coupled to a high single pass conversion of ~70% at the largest current densities and 60 vol% CO in the cell outlet, ideally suited for process cascade involving electro- or thermal catalytic steps. While use of a N2 bleed for internal reference has been known to be critical for accurate evaluation of cell performance, we now propose the experimental N2 vol% in the combined cell outlet and bleed flow to be also a valuable diagnostic tool to recognize and analyze cell failure regimes.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"33 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the stability of ZIBs under extreme operating conditions remains a critical yet often overlooked issue. Here, we present a novel silane-decorated glass fiber separator with engineered physical structures and surface chemistry, facilitating highly reversible and ultra-reliable ZIBs. Silane strengthens the separator, resists stress, and forms heat-insulating char layers under flame, ensuring reliability in extreme conditions. Silane networks also function as fillers that enhance pore uniformity for even Zn2+ flux. The amino groups in silane demonstrate comprehensive management of interfacial anions, cations, water transfer and reaction kinetics. This capability induces Zn2+ to concentrate at the interface, accelerates Zn2+ transfer, reduces deposition barriers, and obstructs water molecules and sulfate ions from participating in parasitic reactions. Consequently, dendrite-free Zn plating/stripping is achieved with 99.4% Coulombic efficiency over 250 cycles, stable charge/discharge performance for 7000 hours, and remarkable cycling stability and flame resistance for Zn//V full batteries. This strategy demonstrates versatility across various separator materials and battery chemistry, offering a promising route to more reliable and higher-performing energy storage systems.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"60 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we present the design of enzyme-inspired zirconium-Fe porphyrinic-based metal-organic framework (MOF) nanosheets functionalized with 5-benzimidazolecarboxylic acid (FeTCPP-NSs-BAA) for CO2RR. Electrochemical performances in H-cell reveal that FeTCPP-NSs-BAA achieves C2H5OH Faradaic efficiencies (FEs) of 79.8% under neutral and 89.2% under acidic conditions, with C2H5OH FEs exceeding 60% over wide potential windows of –0.3 to –0.6 V and –0.3 to –0.8 V, respectively. In flow cell tests under acidic conditions, FeTCPP-NSs-BAA delivers a highest C2H5OH partial current density of 8.1 mA cm–2 with pure CO2, and a C2H5OH partial current density of 5.6 mA cm–2 when using 30% low-concentration CO2. Operando spectroscopic characterizations and theoretical calculations reveal that the superior C2H5OH performance of FeTCPP-NSs-BAA arises from the enzyme-like non-covalent synergistic effects between FeTCPP and the secondary-sphere functionalities of BAA and Zr6 clusters. Specifically, BAA enhances CO2 enrichment and facilitates the formation of tilted *CO adsorption at Fe centers on FeTCPP, which significantly reduces energy barriers for *CO-CO coupling compared to linearly adsorbed *CO. Meanwhile, the subsequent hydrogenation of *CO-CO to C2H5OH can be further accelerated by proton shuttling mediated through hydrogen-bonding networks introduced by Zr6 clusters.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"10 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photocatalytic (PC) hydrogen production technologies offer a unique solution, as hydrogen is produced directly from solar energy and water, without the need for electricity generation. However, cost projections for all photocatalytic designs to date have suggested that they are not cost competitive compared to conventional electrolysis systems manufactured at scale. Herein, we offer the first illustrative benchmark of cost and carbon intensity of hydrogen produced in a Type 2 “Z-scheme” photocatalytic reactor design, which employs suspended semiconducting nanoconductor particles organized into two stacked volumes in a raceway design. The “Z-scheme” system utilizes two separate photoabsorber particles, tuned to drive either the hydrogen evolution reaction or the oxygen evolution reaction individually, connected via a reversible, charge transfer redox couple in solution. The results suggest a highly competitive and scalable technology, that justifies further experimental validation and prototyping in the field.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"97 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144145698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
