This review summarizes the latest developments in single atom materials for CO2 electroreduction, including the application of dual atom catalysts and single atom-cooperating with nanoparticles materials. The article reviews the fine structure of these materials and their relationship with performance, as well as advanced spectroscopic methods for characterization and monitoring of the transformation process. In addition, it discusses the current unresolved issues and future prospects for CO2 electroreduction.
To overcome the effect of greenhouse and the consumption of resource, the CO2 conversion technology offers an effective way, especially electrochemical CO2 reduction reaction (CO2RR). However, CO2RR still faces the challenge of low activity and controversial reaction mechanism. To solve these issues, a series of materials were fabricated. Single atom catalysts possess single active site, high activity and high atom utilization, which can serve as ideal models for studying reaction mechanism and understanding structure-activity relationship. In the review below, we summarize the latest development of single atom materials and their further-developed ones such as dual atom catalysts and single atom cooperating with nanoparticles materials for CO2 electroreduction. Further, the fine structure and the relationship between their structure and performance are reviewed. In addition, we discuss the advanced spectroscopic methods to characterize the structure of single atom-based materials and monitor the transformation during CO2 electroreduction. In the end, the current unresolved is-sues and further outlook for CO2 electroreduction are also discussed.
