摘要

An important goal of heterogeneous catalyst synthesis is the dispersion of the active metal uniformly on a catalyst support,ideally achieving atomic dispersion.Isolated single atoms dispersed on oxide supports provide efficient utilization of scarce platinum group metals (PGMs).The enhanced reactivity of Pt1/FeOx by Qiao et al.[1] generated a lot of excitement in this field and helped set in motion the field of single-atom catalysis (SAC).Since then,we have seen numerous reports of higher reactivity and better selectivity for SACs in a range of catalytic reactions.
