Electrocatalytic reduction of carbon dioxide (CO2) is one of the most promising technologies available to mitigate environmental problems introduced by the continuous increase in its concentration that has occurred since the industrial revolution. This technology also is attractive from the viewpoint that it can be based on carbon-neutral energy by converting CO2 into fuels and value-added chemicals using solar or other forms of renewable energy. In this review, fundamental concepts related to electrocatalysis, the electrical double layer, physical and chemical properties of CO2, the interaction of CO2 with electrode surfaces, and the sources of carbon and proton that underpin this technology are provided. Insights into recent mechanisms proposed for the electrocatalytic reduction of CO2 also are provided along with a survey of progress in the rational design of new electrocatalysts. Discussion on achievements in the field is focused on the variation in products formed by different electrocatalysts and the design strategies that have been introduced to alter the electronic and geometric properties of the electrocatalysts. Finally, recommendations for achieving further advances in electrocatalytic reduction of CO2 in a systematic manner are presented.

电催化二氧化碳还原:从基本原理到催化剂设计

电催化还原二氧化碳(CO 2)是减轻工业革命以来浓度不断增加所引起的环境问题的最有希望的技术之一。从可以通过使用太阳能或其他形式的可再生能源将CO 2转化为燃料和增值化学品的碳中性能源为基础的角度来看,该技术也是有吸引力的。在这篇综述中,基本概念与电催化,双电层,物理和CO的化学性质2,CO的相互作用2提供电极表面,以及支撑该技术的碳和质子源。还提供了对最近提出的电催化还原CO 2的新机制的见解,以及对新型电催化剂的合理设计进展的调查。关于该领域的成就的讨论集中在由不同的电催化剂形成的产物的变化以及已经引入的改变电催化剂的电子和几何性质的设计策略。最后,提出了以系统的方式实现电催化还原CO 2的进一步进展的建议。
