Abstract EN
A nanocomposite with an FeOOH/SiO2 ratio equal to 17.7 wt% and the pertinent matrix, obtained by etching away the nanoparticles through reaction with hydrochloric acid, were investigated by XRD, TGA-DTA, heliostereopicnometry, BET, and TEM techniques.
The study shows the presence in the nanocomposite of ferrihydrite nanoparticles phase with average dimensions around 4 nm.
The FeOOH nanoparticles structure was analyzed by synchrotron X-ray diffraction data using the distribution difference curve method.
The porous structure of the matrix resulting by etching away the nanoparticles differs significantly from that of a pure SiO2 sample obtained by hydrolysis of TEOS under the same operative conditions followed in the nanocomposite preparation.
