Abstract
In this paper the adsorption and oxidation of CO on nanocrystalline Au/γ-Fe2O3, Au/α-
Fe2O3, γ-Fe2O3 and a series of mixed ferrite with MnxZn1-xFe2O4 composition are investigated. The
catalysts were prepared by co-precipitation method and characterized using X-ray diffraction
(XRPD), specific surface (BET), transition electron spectroscopy (TEM) and magnetization
measurements. A temperature programmed desorption (TPD) study of the water and CO interaction
with nanocrystalline adsorbents is presented. The catalytic activities towards CO oxidation
increased in the following order: γ-Fe2O3 < MnxZn1-xFe2O4 < Au/γ-Fe2O3 .
