The effective use of methane as a raw material for industrial processing remains one of the long standing problems in catalysis; methane is the most stable of all hydrocarbons. The elimination of methane and other hydrocarbons from exhaust emissions is of interest due to environmental concerns.
Reinhard Schomäcker, Technische Universität Berlin, Germany, and colleagues present a facile and rapid preparation method for a wide variety of medium surface area perovskite-type catalysts on the laboratory scale. The cellulose templating method allows for catalysts with high phase purity, even at the relatively low calcination temperatures. The prepared perovskites are active in CH4 oxidation.
Their activity ranges between conventionally prepared perovskites and well-developed high surface area perovskites exhibiting a good compromise with regard to the facile preparation method.
