Özet

In the current study, pure MgO nanostructures in the presence of Oleic acid (OA) with 0.2(cc), 0.4(cc), 0.6(cc), 0.8(cc) and 1(cc) as a capping agent were successfully prepared using the ultrasound-assisted method. The effect of the OA concentration on the structural, morphological, optical and porosity properties of prepared nanocomposite materials were studied by Thermogravimetric-differential thermal analysis (TGA-DTA), Field Emission Scanning electron microscopy (FE-SEM), X-ray powder diffraction (XRD), Energy Dispersive X-ray spectroscopy (EDX), UV-Vis spectra and BET (Brunauer, Emmett and Teller). Photocatalytic activity of MgO and OA-doped MgO nanostructures were checked by the degradation of methylene blue (MB) under visible light at optimum pH value. Obtained results show that between samples with different concentrations of OA, the MgO-0.6(cc) OA nanostructures showed the highest degradation performance and decompose 99% of MB at 25 min.
