The commercial viability of this form of reactive carbon capture demands that the electrolyzer effluent that is returned to the capture unit be sufficiently alkaline to effectively capture CO2 from air or a point source. Here, we introduce “electron-alkalinity efficiency” (EA%) to correlate OH– production to electrons consumed during the electrolysis of CO2. We show that the maximum EA% value for CO production is 100%, but is less than 50% for the production of HCOO–, CH4, and C2H4. This outcome implies that the electrolytic production of CO yields the highest CO2 capture efficiency. To support this claim, we modeled a 1-m2 electrolyzer producing CO at a current density of 200 mA cm–2, 100% Faradaic efficiency for CO, and 100% CO2 utilization, resulting in an OH– production rate of 75 mol h–1. No other CO2 reduction products (HCOO–, CH4, and C2H4) generate this level of alkalinity without operating at far more extreme current densities or larger scales. We therefore recommend to “go with CO” for reactive carbon capture.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 5","pages":"2498–2502 2498–2502"},"PeriodicalIF":19.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921386","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}

The choice of electrolyte has a strong impact, whose exact mechanism has yet to be deciphered. Here, we understand the electrolyte effect from the perspective of passivation, the formation of a ZnO layer in the anode during battery discharging. We reveal that the porosity of the layer determines the failure mechanism. Too low porosity blocks ion transport in 4 M KOH, whereas too high porosity renders a large volume change in 6 M KOH and disrupts electron transport, both of which conform to continuum percolation theory. A Ca(OH)2-containing electrolyte results in a medium porosity and enables a stable NiOOH/Zn battery. The work provides not only a quantitative approach to understanding a Zn anode through its microstructure but also a guide to selecting electrolytes for stable Zn batteries.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 5","pages":"2440–2448 2440–2448"},"PeriodicalIF":19.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921378","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}
