Abstract

Abstract : Single-atoms (SAs) can be achieved via electron reduction and nitrogen anchoring that enable the fast nucleation but slow growth of metal ions under N2 plasma compared with a traditional calcination approach. Abstract : A novel, facile and universal N2 plasma approach to form single atom metal sites (Pt, Pd, Ag, Cu, and Co) is proposed. Fast nucleation and slow growth of metal ions under low temperature plasma are the premise to form single atoms. These isolated metal atoms are subsequently trapped by in situ doped nitrogen. We provide a new route to expand the toolbox of single-atoms preparation.
