Titanium dioxide (TiO2) is regarded as an environmentally friendly, easy-to-synthesis, stable and inexpensive catalyst, often as a mildly active catalyst for environmental improvement purposes such as water treatment. In this study, TiO2 was synthesized and characterized using X-Ray diffraction instrument (XRD) to determine the crystal structures, scanning electron microscopy (SEM), equipped with energy-dispersive X-ray spectroscopy (EDX), BET analysis to determine particles size, and FT-IR analysis to determine bonds TiO2. Results show that while the presence of TiO2 nanoparticles at 25o, 38o, 48o at 2θ peaks was detected, TiO was detected at 65o and 70o peaks. According to the results of EDX analysis; Ti, O, Au, and C elements are detected. According to FT-IR analysis, the peak formed at 450 cm-1 shows the presence of TiO2. According to BET analysis; the surface region of TiO2 was identified as 65 m2/g which was significantly higher than that of commercial TiO2 (40 m2/g). The results show that it is acceptable to achieve TiO2 at decrease temperatures according to those used in the literature. Additionally, the characterization of synthesized TiO2 at room temperature is similar compared to the results obtained from previous study results that has been conducted under high temperatures (>400Co). |
