摘要：

Well-dispersed nanocrystalline TiO2 powders were prepared by hydrothermal method from aqueous peroxotitanium acid gel obtained by addition of H2O2 solution to freshly prepared and well-washed titanic acid gel. The obtained TiO2 powders were characterized by FT-IR spectrophotometer, X-ray diffraction (XRD), transmission electron microscope (TEM) and N-2 adsorption. The powders obtained by hydrothermally treating at 393 K for 6 h showed the highest photocatalytic activity for the degradation of aqueous methyl orange solution. (C) 2004 Elsevier B.V.
