Notes:
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. Thecatalysts were prepared by co-precipitation method and characterized using X-ray diffraction(XRPD), specific surface (BET), transition electron spectroscopy (TEM) and magnetizationmeasurements. A temperature programmed desorption (TPD) study of the water and CO interactionwith nanocrystalline adsorbents is presented. The catalytic activities towards CO oxidationincreased in the following order: γ-Fe2O3 〈 MnxZn1-xFe2O4 〈 Au/γ-Fe2O3
