摘要：

TiO2 and doped Ag-TiO2 nanoparticles have been synthesized via a << sol-gel >> technique, starting with titan isopropoxide Ti [OCH (CH3)(2)](4) in the presence of ethanol (>= 99,8% purity), of distilled water (at pH = 9) and of ammonium hydroxide (NH4OH4 30%). The powders obtained were identified as pure TiO2 and doped Ag-TiO2 through XRD and FTIR methods. The nanoparticles of TiO(2 )prepared through our procedure compared well with those of the commercial TiO2 (TiO2 Degussa P25) and they were tested in the photocatalytic degradation of methanol.
