Abstract
The photocatalytic degradation of indigo carmine dye was studied using tungsten
doped BiVO4. Bismuth vanadate powder has been synthesized by sol-gel technique.
The incorporation of W ions into BiVO4 was confirmed by EDX. The photocatalytic
activity was studied using different samples of BiVO4 by variation of pH, concentration
of dye, dose of semiconductor and light intensity.
It has been found that degradation of dye is more effective in presence of W doped
BiVO4, It shows the role of tungsten ions for enhancing degradation of indigo carmine
by reducing the recombination of photogenerated electrons and holes.
