摘要：

X-Ray absorption fine spectroscopy (XAFS) is a material characterization technique developed since 1980s. Because of its sensitivity to the local structure and chemical environment of central absorption atoms, it is very suitable for the characterization of single-atom catalysts. Basing on the principles and features of XAFS technique, this review deeply discussed the unique role of XAFS technology in several application scenarios involving single-atom catalysts, such as electrocatalytic water splitting, fuel cell cathode reaction and carbon dioxide electrochemical reduction. What's more, this review predicted the future application prospects of XAFS technology in the field of single-atom electrocatalysis, expecting to give a hint to further and more specific characterization towards the structure and electrocatalytic mechanism of single-atom catalysts.
