6 wt% of Cu doped ZnO thin films are deposited on ceramic pellets DD3+38% ZrO2. The thin layers were prepared by Different methods autoclave and sol-gel. The characterization of the obtained treated powder was made by the test of the photocatalytic degradation of organic dye Orange II. For this characterization, an aqueous solution of 25 mg/l and a visible light provided by a UV lamp were used. This gave an optimal performance of an interesting discoloration. The degradation rate of Orange II reached 90.5% for Autoclave method and 80.06% for sol-gel method during a period of 7 h with Cu doped ZnO thin layers deposited on porous substrates DD3+38% ZrO₂.
