dc.description.abstract | In the present work, the crystallization of anatase TiO2 nanoparticles (NPs), using different fer2 rite nanoparticles with different chemical composition, dimensions and shape as nucleation seeds, was investigated. In particular, CoFe2O4 , NiFe O4 and Fe3O4 NPs with a volume ratio equal to 1:1000 with respect of TiO2 amount, were used in order to investigate the synthesis of nanocrys-talline tetragonal anatase TiO2 by a hydrothermal synthesis. In addition, Lu2O3 nanoparticles were also used to detect the effect of a non-magnetic nanoparticle on the synthesis and nanocrystal-lization of titnani. For each sample, a deep physical characterization was performed by XRD (with a Rietveld refinement of the structural data), FE-SEM, STEM, and surface area measurement. Furthermore, for some samples the photocatalytic activity was investigated by degradation of methylene blue in aqueous medium, in the framework of a standard ISO 10678:2010 protocol. The hydrothermal synthesis was performed with a 3 hours’ thermal treatment, at a pressure of approximatively 9 bar and a temperature significantly lower (Tmax = 150 C) than the usual temperature necessary to obtain crystalline anatase TiO2 (Tcryst = 350 C). The results give evidence that the mere presence of a nucleation seeds in the hydrothermal reactor, without any particular need for the composition and morphology, leads to crystalline anatase TiO2 nanoparticles with high photocatalytic performances | nb_NO |
