Influence of W-doping on the optical and electrical properties of SnO2 towards photocatalytic detoxification and electrocatalytic water splitting

Band gap tuning of nanomaterials is a current field of interest in order to transform UV-light active catalysts into visible light driven catalysts. Tungsten-doped SnO2 ([email protected]2) nanospheres (NS) with dopant concentration ranging from 0 to 6 mol%, were prepared and characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma optical emission...
