Abstract

We report a two-step synthesis and structural characterization of cobalt tungstate nanostructures and cobalt tungstate/calcium carbonate nanocomposites by the precipitation method. We also investigated the effect of different capping agents such as Tween20, and PEG on morphology and particle size of cobalt tungstate nanoparticles. The photocatalytic activity of the cobalt tungstate/calcium carbonate nanocomposites was studied by degradation of different dyes such as methyl violet (MV), methylene blue (MB), eosin Y (EY), and phenol red (Ph R). The crystal structures, morphology and chemical properties of the as-synthesized cobalt tungstate/calcium carbonate nanocomposites were characterized using X-ray diffraction, scanning electron microscopy, vibrating sample magnetometer techniques and UV–Vis diffuse reflectance spectroscopy.
