The catalyst was prepared applying a thermoelectric polarization process in air to commercially available aSiO<small>₂</small> nanoparticles. Four polarization temperatures were assayed (150, 500, 800 and 1000 °C), the larger structural and chemical changes induced by the polarization treatment being observed at 150 and 500 °C. The polarization at such temperatures reduced considerably the electrical resistance of calcined aSiO<small>₂</small>, while no significant change was detected at 800 and 1000 °C. Polarized aSiO<small>₂</small> was tested as heterogeneous catalysts for the reaction of CO<small>₂</small> with water at mild reaction conditions (120 °C, 6 bar of CO<small>₂</small>, 40 mL of water, 72 h). The highest catalytic activity was observed with aSiO<small>₂</small> polarized at 150 °C, which was attributed to the structural defects induced during the thermoelectric polarization treatment. Thus, CO<small>₂</small> was converted into a mixture of formic acid (39.9%), acetic acid (44.4%) and dioxane (15.7%). Although the catalytic process was not selective, the yields were not only very high but also allowed obtaining a significant amount of dioxane, a product with four carbon atoms, which is very unusual in processes catalyzed by polarized ceramics. In summary, polarized aSiO<small>₂</small> can be used as a sustainable and low-cost raw material to prepare metal-free catalysts by means of a thermoelectric polarization process at 150 °C. This catalyst is capable of capturing CO<small>₂</small> to produce valuable chemical products by applying mild reaction conditions.</p>","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 24","pages":" 5937-5949"},"PeriodicalIF":5.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/se/d4se01389a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142761594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a developing technology, the cost of key components, namely the membrane, electrolyte, and electrodes, present a major hurdle to widespread integration. This work describes the performance of non-woven carbon fiber (NWCF) electrodes derived from low-cost petroleum pitch and produced using a scalable, inexpensive melt-blowing process. Compared to commercial polyacrylonitrile (PAN)-based carbon fiber felt, pitch-based carbon fibers have increased graphitic content, tensile strength, and electrical conductivity. Greenhouse gas emissions for pitch-based carbon fibers are estimated to be significantly lower than that of PAN-based carbon fibers. When RFBs with unoptimized NWCF electrodes are evaluated in zinc iodide electrolytes, the voltage and power density (83 mW cm<small>⁻²</small>) are slightly lower compared to RFBs with PAN-derived carbon felts (104 mW cm<small>⁻²</small>) @ 100 mA cm<small>⁻²</small>. RFBs fabricated with oxidized low-cost NWCF electrodes show nearly identical battery performance to those prepared with commercial PAN-derived carbon felts in vanadium electrolytes (peak power density of 137 mW cm<small>⁻²</small><em>vs.</em> 139 mW cm<small>⁻²</small>, respectively).
