Abstract
CO2-to-CO electrolyzer technology converts carbon dioxide into carbon monoxide using electrochemical methods, offering significant environmental and energy benefits by aiding in greenhouse gas mitigation and promoting a carbon circular economy. Recent study by Strasser et al. in Nature Chemical Engineering presents a high-performance CO2-to-CO electrolyzer utilizing a NiNC catalyst with nearly 100% faradaic efficiency, employing innovative diagnostic tools like the carbon crossover coefficient (CCC) to address transport-related failures and optimize overall efficiency. Strasser’s research demonstrates the potential of NiNC catalysts, particularly NiNC-IMI, for efficient CO production in CO2-to-CO electrolyzers, highlighting their high selectivity and performance. However, challenges such as localized CO2 depletion and mass transport limitations underscore the need for further optimization and development of diagnostic tools like CCC. Strategies for optimizing catalyst structure and operational parameters offer avenues for enhancing the performance and reliability of electrochemical CO2 reduction catalysts.
CO2-to-CO电解槽技术利用电化学方法将二氧化碳转化为一氧化碳,通过帮助减少温室气体排放和促进碳循环经济,提供了显著的环境和能源效益。Strasser等人最近在《自然化学工程》(Nature Chemical Engineering)上发表的一项研究展示了一种高性能的CO2-to-CO电解槽,该电解槽利用NiNC催化剂,法拉第效率接近100%,采用碳交叉系数(CCC)等创新诊断工具来解决与运输相关的故障并优化整体效率。Strasser的研究表明,在CO -to-CO电解槽中,镍基镍基催化剂(尤其是镍基镍基镍基)具有高效CO生产的潜力,突出了其高选择性和高性能。然而,诸如局部二氧化碳消耗和质量传输限制等挑战强调了进一步优化和开发CCC等诊断工具的必要性。优化催化剂结构和操作参数为提高电化学CO2还原催化剂的性能和可靠性提供了途径。
