SYNTESIST AND CHARACTERISATION TiO2-Cu PHOTOCATALYST

Abstract

This study begins with the manufacture of TiO2 -Cu photocatalyst by means of wet impregnation and fotodeposisi, the mole ratio of TiO2: Cu2+ is 100: 0; 99: 1; 98: 2; 97: 3 and 96: 4. Photocatalysts were characterized using SEM, UV-Vis DRS, FTIR and XRD. The results showed has been successfully carried out the synthesis of TiO2-Cu. From SEM characterization shows that the addition of Cu metal will alter the morphology of TiO2 photocatalysts. Based on analysis of UV-Vis DRS, the addition of Cu metal dopant to decrease the energy band gap of TiO2. From XRD analysis appears 2θ value at 29.607 and 48.401 which indicates the formation of monoclinic crystal H2Ti3O7. FTIR analysis results indicate a change in the specific uptake of TiO2 indicating a change in the structure of TiO2
