Supercritical CO2is used as an antisolvent to prepare nanostructured homogeneous mixtures of Cu2+ and Mn3+ with crystallites of 10–20 nm in diameter. Following calcination, this material forms a crystalline tetragonal spinel, CuMn2O4, which is more than twice as active as the conventionally prepared hopcalite catalysts for the oxidation of carbon monoxide.
