Characterization and Testing in Steam Reforming of Methanol (SRM) [Elektronische Daten] [Gregorio Marbán, Teresa Valdés-Solís, Antonio Fuertes] High surface area CuMn2O4 and mixtures of CuO and Mn2O3 were prepared via a novel template technique based on the coagulation—precipitation processes that occur when the metallic cations of salts dissolved in a silica aquagel medium are forced to precipitate by basic reagents. The oxides prepared by this method were tested as catalysts for the methanol steam reforming reaction at 250°C and a very high space velocity (WHSV =27.2h−1). CuMn2O4 with a high surface area (300m2/g) and a tangled structure that apparently resembles the internal surface of the amorphous silica gel was obtained. The catalytic activity of this material is similar to that of the most active catalyst reported in the literature, with the advantage that its stability is enhanced. Contrary to what has been reported for low surface area particles, the physical mixture of copper oxide and manganese oxide nanoparticles prepared by the confined co-precipitation technique displayed a much lower catalytic activity than the spinel.
