Single atom catalysts(SACs)possessing regulated electronic structure,high atom utilization,and superior catalytic efficiency have been studied in almost all fields in recent years.Carbon-based supporting SACs are becoming popular materials because of their low cost,high electron conductivity,and controllable surface property.At the stage of catalysts preparation,the rational design of active sites is necessary for the substantial improvement of activity of catalysts.To date,the reported design strategies are mainly about synthesis mechanism and synthetic method.The level of understanding of design strategies of carbon-based single atom catalysts is requiring deep to be paved.The design strategies about manufac-turing defects and coordination modulation of catalysts are presented.The design strategies are easy to carry out in the process of drawing up preparation routes.The components of carbon-based SACs can be divided into two parts:active site and carbon skeleton.In this review,the manufacture of defects and coordination modulation of two parts are introduced,respectively.The structure features and design strategies from the active sites and carbon skeletons to the overall catalysts are deeply discussed.Then,the structural design of different nano-carbon SACs is introduced systematically.The characteriza-tion of active site and carbon skeleton and the detailed mechanism of reaction process are summarized and analyzed.Next,the applications in the field of electrocatalysis for oxygen conversion and hydrogen conversion are illustrated.The relationships between the superior performance and the structure of active sites or carbon skeletons are discussed.Finally,the conclusion of this review and prospects on the abundant space for further promotion in broader fields are depicted.This review highlights the design and preparation thoughts from the parts to the whole.The detailed and systematic discussion will pro-vide useful guidance for design of SACs for readers.
