Electrochemical deposition of electronically rich Pt single atoms and nanocrystals on porous carbon for enhanced electrocatalysis in strong acids

Abstract

Here, we present an attractive approach to construct electronically rich Pt single atoms and nanocrystals via simple electrochemical cycling. Hollow carbon nanoballoons decorated with cobalt were used as the support, which provided uniform nucleation sites for Pt and served as electron donors. Due to the electronic effect and ultrafine dispersion of Pt, together with the structural advantages, the as-prepared catalyst showed enhanced ORR activity in acidic electrolytes, and its Pt mass activity is superior to that of 20 wt% Pt/C, and shows a better durability.
