TiO2-CNT´s-Cu thin films: photocatalytic applications in the visible region

TiO2, TiO2-Cu, TiO2-CNTs y TiO2-CNTs-Cu films were obtained by Dip-coating technique and 500°C for 1h. The Anatase phase of TiO2 was identified and the TiO2-Cu film also presented the Tenorite secondary phase of CuO. The planes (101) and (200) of the Graphite 2H phase were identified in the films wi...

Description
Summary:TiO2, TiO2-Cu, TiO2-CNTs y TiO2-CNTs-Cu films were obtained by Dip-coating technique and 500°C for 1h. The Anatase phase of TiO2 was identified and the TiO2-Cu film also presented the Tenorite secondary phase of CuO. The planes (101) and (200) of the Graphite 2H phase were identified in the films with CNTs. The crystal size was obtained between 5 to 16 nm. The morphology is homogeneous without pores and without cracks. The bandgap value for TiO2-CNTs-Cu and TiO2 films were 3.22 and 3.48 eV respectively. For photocatalytic evaluation Visible and UV irradiation were used and TiO2-CNTs showed a degradation of 53%.
