  • Efficient oxygen activation limits oxidative catalysis. Here, incorporating single-atom Zr into CeO₂-supported Pt catalysts creates Zr₁–O–Pt₁ structures, significantly enhancing catalytic performance via boosted surface and chemisorbed oxygen activation.

  • Despite its importance in the context of natural gas engines emissions treatment, methane oxidation remains challenging. Now, the authors introduce an approach to stabilize PdOx rafts on ceria by trapping Pt single atoms in the support resulting in a superior catalyst for this transformation.

  • While single-atom catalysts (SACs) have attracted a lot of interest, the nature of the active sites in SACs remains elusive. Here the authors elucidate that depositing single atoms via high temperature synthesis leads to improved reducibility of lattice oxygen on CeO2 yielding low temperature reactivity of Pt catalysts in CO oxidation.

  • There has been a great deal of interest in single-atom heterogeneous catalysis recently. Here, the authors show that industrially relevant lanthanum oxide-doped alumina supports are capable of stabilizing atomically dispersed palladium species, which are evaluated for low-temperature carbon monoxide oxidation.

  • The use of single atoms of platinum group metals on CeO2 is a promising approach to reduce precious metal requirements for automobile exhaust treatment catalysts. Here, the authors discovered that by manipulating the calcination temperatures, they could control the configuration of Pt1 on the CeO2 surface, leading to differences in CO oxidation activity.
