Hetero photo fenton mineralization of toxic dyes by natural sunlight irradiation

Abstract

newline Environmental pollution by toxic compounds has become a topic of newlinegreat importance. Therefore, regulations regarding the release of effluents into rivers newlineand streams have become strict. Heterogeneous Fenton like Fe2(MoO4)3 and FeWO4 newlinecatalyst were synthesized using co-precipitation method and it was calcined at 550°C. newlineThe prepared catalyst Fe2(MoO4)3 and FeWO4 were coated with GO using solid newlinedispersion method for the photocatalytic degradation of organic pollutants. newlineThe structural, functional group, optical and surface morphological properties of the newlineprepared samples were studied using X-ray diffractometry (XRD), Fourier transform newlineinfrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), atomic force newlinemicroscopy (AFM) and diffuse reflectance spectroscopy (DRS). The elemental newlinecomposition of the prepared samples was analyzed using energy dispersive X-ray (EDX) newlineanalysis and elemental color mapping. Photocatalytic activities of the synthesize
