Abstract

In this paper, a method to synthesize anatase TiO2 nanorods by hydrolysis of titanium(IV) isopropoxide(TTIP) in the presence of benzyl alcohol and acetic acid at 210 °C was tested. The novelty of the presentapproach relies on the evaluation of the shape-controlled synthesis of anatase TiO2 nanocrystals via amicrowave-solvothermal method in 45 min. The different TiO2 nanocrystals were obtained by tuningthe TTIP/acetic acid ratio under optimized synthetic conditions and were characterized in detail by X-raydiffraction (XRD), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), micro Raman(together with microphotoluminescence) and FT-IR spectroscopies. The acetic acid coordinated on thenanocrystal surface was removed by the reduction of its carboxyl group via a "super-hydride reaction",and the photocatalytic activity of bare TiO2 nanocrystals, under visible light irradiation, was alsoevaluated: the best performing TiO2 anatase nanocrystals exhibited a discrete photoactivity, completelydegrading Rhodamine B solution in five hours.
