Abstract Solar fuel generation through electrochemical CO2 conversion offers an attractive avenue to store the energy of sunlight in the form of chemical bonds, with the simultaneous remediation of a greenhouse gas. While impressive progress has been achieved in developing novel nanostructured catalysts and understanding the mechanistic details of this process, limited knowledge has been gathered on continuous-flow electrochemical reactors for CO2 electroreduction. This is indeed surprising considering that this might be the only way to scale-up this fledgling technology for future industrial application. In this review article, we discuss the parameters that influence the performance of flow CO2 electrolyzers. This analysis spans the overall design of the electrochemical cell (microfluidic or membrane-based), the employed materials (catalyst, support, etc.), and the operational conditions (electrolyte, pressure, temperature, etc.). We highlight R&D avenues offering particularly promising development opportunities together with the intrinsic limitations of the different approaches. By collecting the most relevant characterization methods (together with the relevant descriptive parameters), we also present an assessment framework for benchmarking CO2 electrolyzers. Finally, we give a brief outlook on photoelectrochemical reactors where solar energy input is directly utilized.

二氧化碳的连续流电还原

摘要 通过电化学 CO2 转化产生太阳能燃料提供了一种有吸引力的途径,以化学键的形式存储阳光能量,同时修复温室气体。虽然在开发新型纳米结构催化剂和了解该过程的机械细节方面取得了令人瞩目的进展,但在用于 CO2 电还原的连续流动电化学反应器方面收集的知识有限。考虑到这可能是扩大这种新兴技术以用于未来工业应用的唯一途径,这确实令人惊讶。在这篇评论文章中,我们讨论了影响流动 CO2 电解槽性能的参数。该分析涵盖电化学电池(微流体或膜基)的整体设计、所用材料(催化剂、支持等)和操作条件(电解质、压力、温度等)。我们强调了提供特别有前途的发展机会的研发途径以及不同方法的内在局限性。通过收集最相关的表征方法(连同相关的描述参数),我们还提出了一个用于基准 CO2 电解槽的评估框架。最后,我们简要介绍了直接利用太阳能输入的光电化学反应器。通过收集最相关的表征方法(连同相关的描述参数),我们还提出了一个用于基准 CO2 电解槽的评估框架。最后,我们简要介绍了直接利用太阳能输入的光电化学反应器。通过收集最相关的表征方法(连同相关的描述参数),我们还提出了一个用于基准 CO2 电解槽的评估框架。最后,我们简要介绍了直接利用太阳能输入的光电化学反应器。
