• Microwave-assisted synthesis of reduced graphene oxide/V$_2$O$_5$ nano-composite as an efficient photocatalyst for dye degradation

In the present study, rapid and green microwave synthesis has been used to synthesize V$_2$O$_5$ and reduced graphene oxide decorated with V$_2$O$_5$, a hybrid nanocomposite (rGO/V$_2$O$_5$), using an inorganic precursor. The synthesized nanocomposite is characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and UV–visible spectroscopy. The photocatalytic activity of V$_2$O$_5$and rGO/V$_2$O$_5$ was studied by degrading methylene blue dye in sunlight. The kinetics of the dye degradation is studied by calculating the rate constant and the half-life of the degradation process. The rGO/V$_2$O$_5$ nanocomposite showed low resistance, thus increasing the diffusion of electrons, which prevents electron–hole recombination and hence enhances photocatalytic activity (80% degradation efficiency) when compared with bare V$_2$O$_5$.
