Structure Regulation of Single‐atom Catalysts for Electrocatalytic Sensing

Abstract Single‐atom catalysts (SACs) have received extensive attention in the fields of electrocatalytic sensing, and in response to the requirements of different sensing systems, a variety of metal single‐atom structures have been emerged. In this review, we at first introduce the current mainstream synthesis methods of SACs, and then focus on the structural regulation strategies of SACs and the structure‐performance relationship generated in electrocatalytic sensing. It is worth noting that we classify the regulation engineering of single‐atom structures and describe the corresponding enhanced performance of electrocatalytic sensing, which makes up for the shortcomings of reviews in this field. Eventually, the opportunities and challenges of SACs based electrochemical sensors are outlined.
