Synthesis and characterization of BaWO4 nanoparticles with the aid of different surfactants and their photocatalyst properties

Nanoparticles sphere-like barium tungstate (BaWO4) have been successfully synthesized via the co-precipitation method process by using barium nitrate hexahydrate, Na2WO4·2H2O and of different surfactants like cetyl trimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS), and ethylene diamine tetraacetic acid (EDTA). The as-synthesized nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (UV–Vis), and energy dispersive X-ray microanalysis (EDX). According to the vibrating sample magnetometer, barium tungstate (BaWO4) nanoparticles indicated a ferromagnetic behavior at room temperature. Photo-catalytic property of barium tungstate was examined by degradation of methyl orange as organic pollutant in water under UV light irradiation. The results showed that methyl orange degradation was about 80% under for 70 min, so the synthesized product can be used as an effective photocatalyst.
