STM and TEM investigation of a technical platinum/graphite catalyst

Abstract

A technical, powder, platinum-on-graphite catalyst has been investigated up to atomic scale by transmission electron microscopy (OAI) and scanning tunneling microscopy (STM). The catalyst had been prepared from a colloidal platinum sol. STM confirms, in addition to spherical particles, the presence of raft structures on the support surface, which had been suggested by the TEM images. The height of these raft structures varies from one to ten atomic layers.
