Emerging low-nuclearity supported metal catalysts with atomic level precision for efficient heterogeneous catalysis

Supported atomically dispersed metal catalysts (ADMCs) have received enormous attention due to their high atom utilization efficiency, mass activity and excellent selectivity. Single-atom site catalysts (SACs) with monometal-center as the quintessential ADMCs have been extensively studied in the catalysis-related fields. Beyond SACs, novel atomically dispersed metal catalysts (NADMCs) with flexible active sites featuring two or more catalytically centers including dual-atom and triple-atom catalysts have drawn ever-increasing attention recently. Owing to the presence of multiple neighboring active sites, NADMCs could exhibit much higher activity and selectivity compared with SACs, especially in those…
