Abstract:

Single-atom catalysts are a class of supported catalysts with high atomic economy and high activity using mutually isolated single metal atoms as the catalytic active center, which have been widely used in energy electrocatalysis. In recent years, researchers have constructed single-atom electrocatalysts with heteroatomic coordination structures by using two or more heteroatoms coordinated to the active center metal atom. It was found that this asymmetric coordination structure effectively modulated the electronic structure of the central metal atom, optimizing the adsorption and desorption energies of the catalytic reaction, and improving the electrocatalytic performance. This paper presents a comprehensive review of the synthesis strategies and characterization techniques of carbon-based single-atom electrocatalysts with heteroatomic coordination structures, and their structure-property correlation for energy electrocatalysis. We give prospects of the future research for this field at the end of the review.
