Abstract:

The dye-pigments and organic compounds are known as significant pollutants in wastewater of textile industrial. Among of treatment technologies, the photocatalysis using TiO₂ nano particles has potential on-site process for removing the dye-pigments and organic compounds, due to no hazardous waste and inexpensive. In this work, the TiO₂ nanoparticles were synthesized by two different methods of hydrothermal and sol-gel. Nanoparticle of TiO₂ synthesized by hydrothermal method contained pure anatase phase as similar as the TiO₂ nanoparticles synthesized by sol-gel method. However, the TiO₂ synthesized by hydrothermal method provided the higher specific surface area and pore volume rather than the another TiO₂. Further, the high efficiency 86% of methylene blue photodegradation was observed during the by using TiO₂ synthesized by hydrothermal method as photocatalyst, whereas the efficiency was only 72% for TiO₂ synthesized by sol-gel method.
