In the present work, the hybrid catalyst films of TiO<sub>2</sub>/CuO containing up to 10% in mol of copper were deposited onto glass surface. Precursor solutions were obtained by citrate precursor method. Films were porous and the average particle size was 20 nm determined by FEG-SEM analysis. The photocatalytic activities of these films were studied using Rhodamine B as a target compound in a fixed bed reactor developed in our laboratory and UV lamp. It was observed that the addition of copper to TiO<sub>2</sub> increased significantly its photocatalytic activity during the oxidation of Rhodamine B. The degradation exceeded 90% within 48 hours of irradiation compared to 38% when pure TiO<sub>2</sub> was used. Moreover, there was a reduction in the particles band gap energy when compared to that of pure TiO<sub>2</sub>. These results indicate that the TiO<sub>2</sub>/CuO films are promising catalysts for the development of fixed bed reactors to be used to treat effluents containing azo dyes.
