Anatase Nano Titanium Oxide Synthesized Using the Hydrothermal Method and its Optical Absorption Properties

Abstract:

Anatase nano titanium oxide was synthesized with Ti(SO₄)₂ as titanium source and stronger ammonia water as precipitant using the hydrothermal method. The samples were characterized by XRD, SEM, TEM and UV-VIS. The results showed that the influence of the increase of the reaction time on as-prepared anatase nano titanium oxide was not obvious when stronger ammonia water was not added to Ti(SO₄)₂ solution. Anatase nano titanium oxide became small markedly under the same conditions when stronger ammonia water was added to Ti(SO₄)₂ solution. Anatase nano titanium oxide of about 20 nm in the diameter was obtained for 48 h with pH=9 at 240 °C by the hydrothermal method. That the size of Anatase nano titanium oxide particles became small was propitious to the blue shift of their absorption peak.
