چکیده مقاله
Abstract TiO2@SiO2 core/shell nanoparticles have been
synthesized by sol–gel method from tetraethylorthotitanate
and tetraethylorthosilicate. The synthesized products were
characterized by X-ray diffraction, scanning electron microscopy,
Fourier transform infrared spectrum, electron
dispersive X-ray spectroscopy and ultraviolet–visible. The
results revealed that compared to SiO2 and TiO2, TiO2@SiO2
core/shell nanoparticles display smaller crystal size
and greater band gap energy. The photocatalytic activity of
the synthesized products has been compared in the photodegradation
activity of methylene blue.
