Enhanced Photocatalytic Degradation of Azo Dyes Using Hydrothermally Synthesized Vanadium Pentoxide Nanomaterials

by Lakshmaiya N.

Water and Wastewater Treatment

This study employed a simple hydrothermal (HT) approach to synthesize vanadium pentoxide (V 2O 5) nanomaterials. The inherent limitations of V 2O 5, including low quantum efficiency and insufficient light sensitivity, restrict its potential for enhanced photocatalytic activity. The study...
