Synthesis, characterisation and catalytic activity of V2O5 nanoparticles using Foeniculum vulgare stem extract

Abstract

A green synthesis route of metal oxide has been developed to synthesize the V2O5 nanoparticles. V2O5 was synthesized using Foeniculum vulgare stems extract (FSE) and ammonium monovanadate as precursors. The role of secondary metabolite compounds affect the particle size of V2O5. The crystalline phase and crystallite size of V2O5 were investigated by X-Ray Diffraction (XRD) with the orthorhombic crystalline phase and the average crystallite size around 78.6 nm. The presence of functional groups was evaluated by Fourier Transform Infrared (FT-IR). The morphology, particle size, and chemical composition of V2O5 were analyzed by Scanning Electron Microscopy (SEM), Tunneling Electron Microscopy (TEM) and Energy Dispersive X-Ray (EDX). V2O5 nanoparticles show a good catalytic activity for the reduction of methylene blue (MB).
