Abstract

The photo degradation of Congo red (CR) with TiO2 and TiO2 doped with Pd was investigated. The TiO2 and Pd doped TiO2 nanoparticles were created through solution combustion with glycine as the fuel, and their band gap was determined using UV absorption spectroscopy. All experiments were conducted in natural Sunlight and UV light. Both nanoparticles degraded rapidly at 20 ​ppm dye concentration and 0.1 ​g/1000 ​ml catalyst concentration. It demonstrates that synthesized TiO2 and Pd doped TiO2 nanoparticles can degrade Congo red in an aqueous solution.
