Au=Fe2O3(Au : Fe = 1 : 50) catalyst was prepared by the co-precipitation method. The coprecipitate was studied by using di erential thermal analysis (DTA) and di erential thermal gravimetric analysis (DTGA). The structure of the sample was investigated by using X-ray di raction (XRD) and transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). The particle size was determined to be within the range of 1.5 and 8 nm. Results of the study for catalytic properties showed that T1=2 for CO and H2 oxidation were 317 and 405 K respectively.
