Synthesis and characterization of heterostructured nanoparticle for efficient photocatalytic performance for dye degradation

Abstract

Abstract This paper focusses on the synthesis of cobalt vanadate (CoVO4) nanoparticles (NPs) by precipitation method. This was further augmented by assistance from microwave. Nanotechnology has been a wonderful tool with the promising application in different fields of life. The CoVO4 NPs synthesized by microwave assisted precipitation method was characterized by advanced techniques such as X-ray powder diffraction (XRD), Energy dispersive X-ray analysis (EDX), Scanning electron microscopy (SEM), Ultraviolet visible spectroscopy (UV–vis) techniques. Rhodamine B (RhB) dye was used to evaluate the photo catalytic activity (PCA) of NPs by degradation of dye. The conditions were optimized for maximum degradation of dye. The NPs were in the nano flowers form and the size was ≤100 nm. The results regarding degradation of RhB was through PCA were promising; 83% dye was degraded at pH 10, reaction time 160 min and catalyst dose 1 g. It may conclude that the synthesized NPs could further be employed for possible treatment of industrial effluents particularly textile industry.
