Facile Synthesis, Characterization and Enhanced Photocatalytic Activities of NiWO₄/Nitrogen Doped Reduced Graphene Oxide Nanocomposites.

In this study, we report the synthesis of NiWO₄/nitrogen doped reduced graphene oxide nano composite by one-pot hydrothermal method. The NiWO₄ nano particles were dispersed uniformly on graphene sheets. The as prepared NiWO₄, NiWO₄/5% rGO and NiWO₄/N-5% rGO composites were analytically characterized by Powder X-ray diffraction (XRD), Raman spectroscopy, Diffuse reflectance spectroscopy (DRS-UV), Scanning electron microscopy (SEM) and N₂ adsorption-desorption isotherm.

BiVO /N-rGO nano composites as highly efficient visible active photocatalyst for the degradation of dyes and antibiotics in eco system.

Herein, we report the synthesis of novel nitrogen doped reduced graphene oxide/ BiVO photo catalyst by single step hydrothermal method. The physicochemical properties of the catalysts were characterized using XRD, N adsorption-desorption, Raman, XPS, SEM TEM, DRS-UV and EIS techniques. The synthesized catalysts were tested for their catalytic activity in the photo degradation of some harmful textile dyes (methylene blue & congo red) and antibiotics (metronidazole and chloramphenicol) under visible light irradiation.
