Abstract

Research on synthesis of copper and sulfur-doped TiO2 with sol-gel method has been done. The study was followed by product characterization with XRD and DR UV-Vis spectroscopy. Photocatalist Cu-S TiO2 has been applied in degradation of phenol initiated by energy sources. Cu-S TiO2 synthesis was performed in one reaction step with TiCl4 as precursor, Cu(NO3)2.3H2O, and H2SO4. Calcination step follows in 450 0C within 4 hours. The method result in nanocrystallin anatase material of Cu-S TiO2 of 8.77 nm in size whose band gap of 1.9 eV decrease from former value of 3.2 eV. By the energy level, photocatalytic proces might be conducted after initiating the material with sun light exposure. Evaluation of the Cu-S TiO2 capability in degrading phenol concentration show that after initiating with UV, visible, and sun light within 6 hours the treatment result in decreasing of phenol concentration by 84.24%, 83.74% and 66.26%, respectively. Keywords: Synthesis, characterization, TiO2, Cu-S TiO2, phenolFC Telah dilakukan sintesis fotokatalis TiO2 dengan doping tembaga dan sulfur dengan metode sol gel dan karakterisasinya menggunakan X-RD dan DR UV-Vis. Fotokatalis­ Cu-S TiO2 terhasil diaplikasikan pada degradasi senyawa fenol menggunakan berbagai energi foton. Sintesisi Cu-S TiO2 dilakukan dalam satu tahap reaksi menggunakan prekrusor TiCl4, Cu(NO3)2.
