fabricant and characterization of srwo4 and novel silver-doped srwo4 using co-precipitation method: their photocatalytic performances for methyl orange degradation

A simple co-presipitation method has been developed to synthesize srwo4 and ag°-srwo4 micro/nanostructures with different morphologies, including platelet-, star- and flower-like, in the presence of na(b(c6h5)) as surfactant. the formation of platelet-, star- and flower-like shapes of particulate system was examined by electron microscopy technique. the products were characterized by x-ray diffraction, scanning electron microscope, uv-vis absorption, energy dispersive x-ray and fourier transform infrared spectra. the scheelite type tetragonal structure of all the synthesized compounds was revealed by powder x-ray diffraction analysis. the influence of surfactant concentration (sodium tetraphenylborate as new surfactant) on the size and morphology of products was investigated. finally, a good photocatalytic activity was first discovered of the ag°-srwo4 microcrystals for the degradation of methyl orange dye after 100 min under uv-vis light. hence, from the present investigation it was observed that the doping of ag in srwo4 will yield a new kind of multifunctional material for fabricating electronic devices
