Preparation of V2O5 and SnO2 Nanoparticles and Their Application as Pollutant Removal

Abstract

Vanadium pentoxide and Tin dioxide nanoparticles were prepared by hydrothermal methods to remove methylene blue (MB) and bromothymol blue (BTB) dyes). First the prepared nanoparticles were heated at different temperature (90 o C and 500 o C). Then these nanoparticles were characterized by different methods such as UV/Visible, FT-IR Spectroscopy, X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), and Scanning Electron Microscopy (SEM). Our results explain that vanadium pentoxide nanoparticles appeared high remove activity against both types of organic dyes (MB and BTB) compared to tin dioxide nanoparticles. Furthermore,vanadium pentoxide heating at 90 o C has grain size (86.02 nm) more than that of Tin dioxide (48.02 nm) at same temperature. The activity of vanadium pentoxide is more than that of tin dioxide.may be related to high ionic potential (0.073), compared with Tin dioxide (0.048).

“…In addition to energy storage, vanadium pentoxide is used in environmental cleanup. Research has shown its efficacy in removing pollutants, particularly in breaking down organic dyes, highlighting its promise for water treatment [11]. Vanadium pentoxide nanoparticles have been studied for their catalytic characteristics in detecting hydrazine, showing promise for use in sensing applications [12].…”
