Preparation of preferentially exposed poison-resistant Pt(111) nanoplates with a nitrogen-doped graphene aerogel†
Abstract
A poison-resistant and highly catalytically active Pt(111) lattice on ultrathin Pt nanoplates (Pt(111)NPTs) with a large ratio (28%) of surface active to sum Pt atoms is obtained with a dense small pore N-atom doped aerogel (NGA) featuring a large specific surface area and high N content in the graphene skeleton.
