电化学CO2还原是一个复杂的过程，有许多竞争的产品，但自然界已经发展出克服这些问题的方法。该观点将自然界中观察到的图案与可用于合成系统中的策略联系起来，以提高CO2还原的选择性。将CO2电化学还原为有用的燃料和化学原料为碳中性经济的转化提供了巨大的希望。然而，产品选择性的挑战继续限制电催化系统的实际应用。在这个角度来看，我们概述了热力学和动力学因素的改进催化剂的设计CO2固定和碳-碳键的形成，并绘制合成系统和天然酶进行类似的转换之间的相似之处。通过确定自然界中高效CO2转化反应的主要特征，可以构建合成催化剂，以利用类似的化学原理。鉴于生物启发分子设计的先前成功，化学，生物和材料科学领域之间增加的动态相互作用将以协同方式推进催化剂的开发。
Electrochemical CO2 reduction is a complex process with many competing products, yet nature has evolved ways to overcome these issues. This Perspective makes connections between the motifs observed in nature and strategies that can be employed in synthetic systems for the advancement of selectivity in CO2 reduction.The electrochemical reduction of CO2 into useful fuels and chemical feedstocks offers great promise for conversion to a carbon-neutral economy. However, challenges in product selectivity continue to limit the practical application of electrocatalytic systems. In this Perspective, we outline the thermodynamic and kinetic factors for the design of improved catalysts for CO2 fixation and carbon-carbon bond formation, and draw parallels between synthetic systems and natural enzymes that perform analogous transformations. By identifying the primary features that underpin the highly efficient CO2 conversion reactions seen in nature, synthetic catalysts can be constructed to take advantage of similar chemical principles. Given the demonstrated prior success of bio-inspired molecular design, increased and dynamic interactions between the chemical, biological and materials science fields will advance catalyst development in a synergistic fashion.
