| Description |
TiO2 NPs synthesized via aqueous route shows better photocatalytic activity as compare to doped TiO2 NPs. The presence of dopants inhibits the recombination of exciton. The photocatalytic activity of the nanomaterial have been reduced because of less adsorption sites are available for MB dye due to increase surface coverage of nanomaterial by increase in Cr loading and thus less degradation is shown by doped material. Undoped TiO2 nanoparticles shows complete degradation of MB in 90 min, whereas doped TiO2 takes 120 min for complete degradation. The results suggested as higher concentration of dopant material leads to reduction in photocatalytic efficiency.
