Abstract

Platinum (Pt) nanoparticles were synthesized with room-temperature ionic liquid (RTIL)-sputtering method under dry N<sub>2</sub> or Ar atmosphere. The resulting Pt nanoparticles were well-dispersed in trimethyl-<i>n</i>-propylammonium bis((trifluoromethyl)sulfonyl)amide RTIL without any additive like dispersant. Electrocatalytic activity of the Pt nanoparticles embedded on a glassy carbon electrode (GCE) toward oxygen reduction reaction was examined. It was then found that the catalytic activity increases with increment of heat temperature for embedding the Pt nanoparticles onto GCE if the nanoparticles are synthesized under Ar atmosphere.
