	Article:	MORPHO-STRUCTURAL AND PHOTOCATALYTIC PROPERTIES OF SnO₂ NANOPARTICLES. Authors: MARIA ŞTEFAN, OVIDIU PANA, CRISTIAN LEOȘTEAN, ADRIANA POPA, DANA TOLOMAN, SERGIU MACAVEI, DIANA LAZAR, LUCIAN BARBU-TUDORAN.


	Abstract: SnO₂ nanoparticles were successfully synthesized by precipitation method, in the presence of hexadecyltrimethyl ammonium bromide (CTAB) and polyethylene glycol 600 (PEG 600) as surfactants. The obtained SnO₂ nanoparticles were characterized by X-ray diffraction (XRD), porosity and surface area measurements (BET), high resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS). Also, photocatalytic properties toward degradation of Rhodamine B (RhB) were investigated. It was found that morpho-structural properties are influenced by the preparative conditions of doped SnO₂nanoparticles. Keywords: SnO₂; nanoparticles; photocatalytic properties
