Photocatalytic degradation of organic dye by sol-gel-derived gallium-doped anatase titanium oxide nanoparticles for environmental remediation

摘要: Photocatalytic degradation of toxic organic chemicals is considered to be the most efficient green method for surface water treatment. We have reported sol-gel synthesis Gadoped anatase TiO2 nanoparticles and photocatalytic oxidation dye into nontoxic inorganic products under UV irradiation. Photodegradation experiments show very good activity Ga-doped with almost 90% efficiency within 3 hrs irradiation, which faster than undoped samples. Doping levels created bandgap act as trapping centers suppress photogenerated electron-hole recombination proper timely utilization charge carriers generation strong oxidizing radicals degrade dye. found follow pseudo-first-order kinetics apparent 1st order rate constant around 1.3 × 10-2 min-1. The cost-effective, sol-gel-derived :Ga can used efficiently light-assisted molecules in environmental remediation.
