Abstract

Ultra-fine gold particles supported on iron oxide have been synthesized by coprecipitation and subsequently heat treated in air at temperatures ranging from 200°C to 700°C. Structure analyses have revealed variations in the degree of crystallinity of the iron oxide support as well as gold particle size and size distribution with heat treatment temperature. In addition, lattice parameters of gold particles were observed to deviate up to ten percent from the bulk value. We discuss these observations in light of a total minimization of the energy of the system (support plus particles).
