Porous nanocomposite of binary copper manganese oxides were prepared by a modified redox method in the presence of colloidal layer silicates and their catalytic activity for carbon monoxide removal at ambient temperature evaluated. At first, colloidal layer silicate were prepared by swelling synthetic layer silicate(Laponite RD) in de-ionized water, then potassium permanganate(KMnO4) was dissolved into the colloidal solution, subsequently a mixed aqueous solution of manganese(II) acetate and copper(II) acetate solution was added dropwisely to a solution of KMnO4 under vigorous stirring. The resultant precipitate was filtered, washed, and dried at 120 ℃, and finally heat treated in air for 2 hours at 280 ℃. As the layer silicate particles exist in the coprecipitation solution, the resulting composite powders exhibited increased specific surface areas and pore volumes along with the enhanced activity of CO removal at ambient temperature.
