Nano-titanium oxide doped with gold, silver and palladium – synthesis and structural characterization
Abstract
Nanotitania doped with noble metals (Au/TiO2, Ag/TiO2, Pd/TiO2) has been synthesized by mild hydrolysis of the mixture of metal salts or complexes and (iPr-O)4Ti. After thermal decomposition of the obtained precursors, nanomaterials have been formed. Morphological characterization of the nanomaterials has been provided by Scanning Electron Microscopy (SEM) and stereological analysis, determining BET specific surface area, BJH nanoporosity (pore volume, pore size). We found, that the structure of nanomaterials (size of nanoparticles and agglomerates) depended strongly on the method of (iPr-O)4Ti hydrolysis. A minor dependence was observed on a kind of solvents and compounds being precursors of noble metals. A presence of doping metal nanoparticles was confirmed by transmission Electron Microscopy (TEM) and Energy Dispersive X-ray Spectroscopy (EDX). An identification of the nanomaterial phases was given by X-ray Diffraction (XRD). According the XRD patterns, Ag/TiO2 and Pd/TiO2 products with doping metals in an oxidized form, contain Ag-Ti and Pd-Ti phases. Peaks of metal oxides Ag2O and PdO are absent in the XRD patterns. The average size of TiO2 nanoparticles is situated in the region of 20–60 nm, whereas metals are present as about 10-15 nm sized and fine nanoparticles.
