Abstract

Nanocomposite Titanium Dioxide (TiO₂) doped Copper (Cu), Cu-TiO₂ is synthesized by the impregnation method. This study aims to determine the effect of adding Cu to the TiO₂ structure. The 1, 3, and 5 Cu with% TiO₂ dissolved in 50 ml of deionized water, and 3 grams of TiO₂ added. The compound is then stirred for 2 hours at 90^oC and dried in an oven at 110^oC for 30 minutes. Drying samples were calcined at 500^oC for 3 hours. Cu-TiO₂ nanocomposites were characterized by XRD, SEM-EDX Mapping, and FTIR. The XRD analysis results show that Cu-TiO₂ nanocomposite has a high level of crystallinity and has an anatase phase structure. The size of TiO₂ crystals decreased with Cu doping and increased from 49.66 nm to 49.68 nm, with an increase in the composition of the doping mass of Cu. The SEM-EDX Mapping results show that all samples tend to clot, and Cu dopants evenly distributed on the surface of TiO₂. FTIR analysis explained the presence of hydroxyl ions in the sample marked with the appearance of the absorption peak at 1658.78 cm^-1 associated with OH bending of Ti-OH.
