Optical and photocatalytic properties of novel heterogeneous PtSe2-graphene/TiO2 nanocomposites synthesized via ultrasonic assisted techniques.
Novel material PtSe2-graphene/TiO2 nanocomposites were successfully synthesized through a facile ultrasonic assisted method. The prepared composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) with an energy dispersive X-ray (EDX),transmission electron microscopy (TEM), Raman spectroscopic analysis, UV-vis absorbance spectra and UV-vis diffuse reflectance spectra (DRS) analysis were obtained. The catalytic behavior was investigated through the decomposition of rhodamine B (Rh.B) as a standard dye. Enhanced photocatalytic activities were observed by increasing the weight% of graphene in the PtSe2-graphene/TiO2 nanocomposites. We observed that the coupling of TiO2 with PtSe2-graphene alter the optical properties by observing a precise band gap in the visible range.
