Abstract

Characterization of small platinum particles in the Pt/graphite catalyst is done using high-resolution dark-field electron microscopy and single-particle electron diffraction. Two types of hexagonal-shaped particles were found. Both are shown to correspond to a three-dimensional cubo-octahedral shape. The first type has a (111) face in contact with the (0001) face of the graphite surface. The second type has a (110) face parallel to the (0001) face of the support surface. The faceted Pt particles are bounded by (100) and (111) crystallographic planes, which provide specific sites for a catalytic reaction.
