How synthetic methods of single-atom electrocatalysts affect the catalytic performance of carbon dioxide reduction

Abstract

Anthropogenic accumulation of atmospheric carbon dioxide (CO₂) rises many environmental issues, including global warming, ocean acidification, and glacial ablation. Electrocatalytic carbon dioxide reduction reaction (CO₂RR) is an efficient approach to reducing atmospheric CO₂ concentration as well as producing value-added chemicals. Single-atom electrocatalysts (SAECs) have attracted much attention due to their remarkable electrocatalytic performance. The synthetic methods of SAECs can significantly affect the structure and, thus the catalytic performance of energy conversion reactions like CO₂RR. However, the underlying mechanism of the impacts has been largely overlooked. The focus of this short review is to reveal the correlation of synthetic methods with the catalytic performance of SAECs for CO₂RR and provide insights for future research in this field.
