| Abstract: | Single-atom catalysts (SACs) not only extend the research of heterogeneous catalysts from nanoscale to atomic scale, but also help us to study and understand the heterogeneous catalytic reactions from atomic level. In addition, SACs make it possible to further improve atom utilization rate of active Pt-group metals and effectively reduce the cost of catalysts. The preparation methods and characterization techniques for atomically dispersed Pt-group metal catalysts in recent years were reviewed. And the critical control parameters and the scope of applications of different preparation methods, as well as characterization techniques, and the existing problems and challenges were also summarized. Furthermore, based on the integrating innovation of different characterization techniques, putting forward prospective for controllable preparation of Pt-group metal based single-atom catalysts into industrial application was also discussed. |
