Room temperature solid-state transformation from image to image by ozone oxidation

The mixed silver–copper oxide, image has been previously synthesized by electrochemical oxidation of suspensions of the precursor image and also by direct oxidation/coprecipitation of soluble salts. This work shows how the transformation from image to image can take place in solid state at room temperature by ozonization of the precursor. The final phase is overstoichiometric in oxygen but shows the same structural features of the firstly described phase image. The maximum content of oxygen achieved is 4.34 per unit formula.
