ResumoA series of pure and mixed Mn and Cu oxides were prepared by calcination of MnCO3 and CuCO3·Cu(OH)2 at different temperatures, (250, 500, 750 and 1000°C) for 4 h in air. Pyrolyses of pure and mixed solid salts were investigated using the thermal analysis (DTA and TG) technique in a flow of air. Also, the calcined samples were analyzed for different species using X-ray diffraction (XRD). A solid-state reaction model accounting for the Mn oxide–Cu oxide interaction in mixed systems is discussed. The catalytic activity of the thermal products of pure and mixed solids was tested in H2O2 decomposition as a model reaction.
