Facile Synthesis Of G-cn/ato Hybrid Nanocomposite And Its Application For The Photodegradation Of Organic Compound

Photodegradation of organic pollutants using nanoparticles with suitably band gap is one of the most studied technologies in last few decades. Herein we prepared antimony-doped tin oxide (ATO) nanoparticles with an average size of ~6 nm by co-precipitation and subsequent heat treatment. ATO was combined with thermally synthesized g-C3N4 and the resulting g-CN/ATO hybrid nanocomposite was utilized for the decomposition of salicylic acid (SA) in aqueous solution. The materials were characterized using N2 adsorption/desorption (BET), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR) and the progress of the photocatalytic degradation reaction was measured by using UV-Visible spectroscopy. The rate constant measurements showed that the rate of degradation of SA is enhanced with hybrid nanocomposite.
