Controllable synthesis of SmVO_4 nanoparticles with different morphologies by wet chemical route

摘要

In this work various morphologies of samarium vanadate (SmVO4) nanostructures were synthesized via chemical reaction between samarium nitrate hexahydrate and ammonium metavanadate. The effect of different surfactants such as sodium dodecyl sulfate, ethylene diamine tetraacetic acid and polyvinylpyrrolidone on the morphology of samarium vanadate nanostructures was investigated. Photo-catalytic property of SmVO_4 was examined by degradation of methyl orange as organic pollutant in water under UV light irradiation. Nanostructures were characterized by X-ray diffraction, energy dispersive X-ray microanalysis, diffuse reflectance spectroscopy and scanning electron microscopy. According to the vibrating sample magnetometer result, SmVO_4 nanoparticles indicated a paramagnetic behavior at room temperature.
