One promising approach for decarbonization involves electrochemical generation of concentrated acid and base. This effectively decouples the carbon capture-release process from the electrochemical cell, avoiding the kinetic limitations associated with reactions involving CO2. Designing an electrochemical acid-base generator with high current efficiency and low energy cost is challenging. Following investigations of the crossover rates of protons and hydroxide ions through ion-exchange membranes, we designed a multichambered electrochemical cell for generating weak acid and strong base, which significantly suppressed acid-base crossover. By equipping the center chamber with a serpentine flow field, we achieved acid-base production at high concentrations (> 1 M) and high Coulombic efficiency (> 95%) while maintaining relatively low energy costs. With this device, we demonstrated carbon management examples of simulated flue gas capture, direct air capture, and green production of slaked lime, as one step toward green cement production. The key components of the prototype can be adapted for use in other electrochemical cell designs, ensuring high efficiency in concentrated acid-base generation in other application scenarios.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"24 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635183","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}

We herein propose and validate a strategy that could simultaneously address these challenges based on synchronous dimension-crystallization engineering in 2D/3D tin perovskite films. Different from the conventional dimension engineering that relies on precise n-phase control, the employed 4-guanidinium benzoate hydrochloride (GBAC) in present work has an unforeseen desorption effect between phenylethylamine (PEA) and the perovskite, which leads to a direct transition from the 2D to the 3D phase. It is also found that introducing GBAC results in the formation of elongated organic-inorganic hybrid chains, which improve the crystallization process of the films by accelerating both nucleation and growth rates. By virtue of these merits, the resulted tin PSCs achieve a champion power conversion efficiency of 15.02%, together with an exceptional long-term stability with 87% remaining after 4000 h and 80% after 400 h under working at the maximum power point.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"20 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627400","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}

However, a novel approach utilizing spontaneous self-passivation of plated Zn (101) offers the potential to harness its favorable kinetics and stronger Zn-Zn bonding for battery applications. Here, we present a high-utilization and fast-kinetics Zn anode by promoting selective (101) facet growth and achieving spontaneous passivation of the underlying Zn plating. A non-stoichiometric Sn-O system is selected as the modification material because of its ability of engineering crystal structures (amorphous, rutile, layered) and manipulating electrical polarity (n-type vs p-type). The optimized SnO1.17 saturates dangling bonds of Zn (101), benefiting the preferential growth of well-aligned Zn (101) planes. Besides, the Zn2+ plating location is altered underlying the interphase due to synergetic effects of lower Zn2+ migration barriers of the layered structure and electron-blocking properties of SnO1.17. Consequently, a high Zn utilization ratio of over 91.5% is achieved for 800 hours, with an impressively low overpotential of 43 mV. Furthermore, an anode-free system combining a ZnMn2O4 cathode and a SnO1.17@Cu anode retained 81.6% capacity after 200 cycles.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"40 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618815","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}

Nevertheless, the interfacial stability and cyclic reversibility for Zn anode are impeded by the unregulated growth of Zn dendrites and active H2O-induced side reactions. Here, an organic compound bis(2-hydroxyethyl) disulfide (BHED) is proposed as a multifunctional and efficient electrolyte additive, characterized by hydrophilic hydroxyl groups and dynamic sacrificial bonding disulfide bonds. It is discovered that BHED can optimize the Zn2+ solvation structure and construct a water-blocking barrier on the Zn anode surface. Besides, BHED undergoes reductive decomposition, promoting the in-situ formation of a self-assembled monolayer (SAM) with highly active zincophilic sites on the Zn anode surface. Notably, the unique SAM serves a dual function. It stabilizes the anode/electrolyte interface by trapping active H2O and guides Zn2+ to deposit uniformly and orderly onto the (002) crystal plane. As a result, the Zn||Zn symmetric cells containing BHED additive achieve Zn2+ uniform plating/stripping exceeding 6300 h at 0.5 mA cm-2 and 0.5 mAh cm-2. Furthermore, the Zn||NH4V4O10 full cells maintain a capacity retention rate of 73.9% following 3000 stabilized cycles at 5 A g-1.

Here, we propose an ultrathin, water-repellent, Zn2+-selective layer to prevent the undesirable water layer and avoid the water penetrating and dissolution. This interface, with an ultrathin thickness of 16.9 nm, is composed of a water repellent didodecyldimethylammonium organic top layer and an open three-dimensional framework structure of inorganic layer with subnanometer pores and redox-active Fe centers that function as faradaic ion pumps, facilitating rapid Zn2+ transport. This ultrathin solid contact layer acts as semi-permeable membrane with low water permeance of 0.000028 mol m-2 h-1 Pa-1, while facilitating fast Zn2+ transport, thus suppressing hydrogen evolution. As a result, this layer enables over 10,000 stable plating/stripping cycles at 5 mA cm-2 with an average Coulombic efficiency of 99.91%. At a high rate of 150 C, the Zn-I2 cell operates for an unprecedented 65,000 cycles.
