The electrochemical reduction of CO₂听(颁翱₂RR) is a promising approach to maintain a carbon cycle balance and produce value-added chemicals. However, CO₂RR technology is far from mature, since the conventional CO₂RR electrocatalysts suffer from low activity (leading to currents <10鈥卪A鈥塩m^鈭�2聽in an H-cell), stability (<120鈥卙), and selectivity. Hence, they cannot meet the requirements for commercial applications (>200鈥卪A鈥塩m^鈭�2, >8000鈥卙, >90鈥�% selectivity). Significant improvements are possible by taking inspiration from nature, considering biological organisms that efficiently catalyze the CO₂聽to various products. In this minireview, we present recent examples of enzyme-inspired and enzyme-mimicking CO₂RR electrocatalysts enabling the production of C₁聽products with high faradaic efficiency. At present, these designs do not typically follow a methodical approach, but rather focus on isolated features of biological systems. To achieve disruptive change, we advocate a systematic design methodology that leverages fundamental mechanisms associated with desired properties in nature and adapts them to the context of engineering applications.
