Abstract

ConspectusSingle-atom catalysis has become one of the most active frontiers in catalysis in the past decade. This concept not only gives birth to a new kind of heterogeneous catalysts featuring well-defined isolated active sites and strong covalent (or electronic) metal-support interaction, which deliver unique catalytic activity, selectivity, and stability distinct from their nanoparticulate counterparts, but also together with the principles and concepts in history, reshapes our understanding of heterogeneous catalysis and drives the catalysis research from the nanoscale and subnanoscale to the more precise atomic scale.Due to the extremely high free energy, the isolated gaseous metal atoms cannot survive…
