Study on the preparation and catalytic activity of gold nanoparticles supported on Fe203

Abstract

   Au/Fe2O3 catalyst was prepared by the coprecipitation method. The formation process of Au/Fe2O3 was investigated by DTA, TGA, DrTGA, TEM, HRTEM and XRD. The results show that the gold particle size of the sample calcined at 300^oC is in the range 1.2 - 7.8 nm. The catalytic oxidation of CO and H2 was determined.
