Abstract
AbstractBiVO4 have been proven to be one of the most promising photocatalyst for degradation of organic dyes and also exhibit good electrochemical performances in heavy metal detection. Herein, we have developed a simple, economic and low‐cost combustion synthesis of BiVO4 nanoparticles using bismuth nitrate as an oxidiser, lemon (Citrus Limon) juice as fuel. The prepared nanoparticles were characterized by Powder X‐ray diffractometer (PXRD), Fourier Transform‐Infrared spectroscopy (FTIR), Diffused Reflectance Spectroscopy (DRS), Photoluminescence Spectroscopy (PL), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) analytical techniques. Flower‐like morphology BiVO4 nanoparticles were observed for higher ratio of fuel (Citrus Limon). BiVO4 nanoparticles showed an excellent photocatalytic activity towards degradation of Indigo Carmine dye in solution. Further, BiVO4 modified electrode was examined for the detection of Hg (II) using electrochemical techniques.
