Synthesis and properties of single-atom catalysts

Single-atom catalysis is a useful and powerful technique with remarkable performance, a lower cost, and significant catalytic activity and selectivity. In single-atom catalysis, supported single-atom catalysts (SACs) may contain individual isolated atoms that are dispersed on, and coordinated with, the surface atoms having appropriate supports, which not only enhance the atomic efficiency of metals but also provide a fundamental strategy to alter the activity and selectivity of various catalytic reactions. This will highlight the attributes and properties of single-atom catalysis and also summarize the advancements in SACs with a focus on the structure or design of highly stable and active single atoms.
