TiO₂nanoparticles have been prepared using sol-gel method from titanium(IV), isopropoxide, isopropyl alcohol, ammonia hydroxide as precursors at mild condition without any post heat treatment for crystallization. The nanocrystalline TiO₂powders were composed of rutile form TiO₂by X-ray diffraction. The size of nanoparticles was examined by transmission electron microscopy and is about 10–15 nm, and the Brunauer-Emmett-Teller specific surface area of the rutile nanopowder makes up 159.6 m²/g. Photochemical degradation of phenol solution under ultraviolet irradiation of the synthesized TiO₂nanoparticles has been carried out
