Morphology and Degradation Kinetics of N-Doped TiO<sub>2</sub> Nano Particle Synthesized Using Sonochemical Method

Abstract

Nano particle of N-doped TiO2 with the size of 21.42 nm was successfully created using sonochemical method. Concentration of Nitrogen (N) doping on TiO2 was calculated using mole ratio of Urea and TTiP. Doping variations were performed by doping 5% to 9% N, and did not change the crystallite size and strain. The nanoparticle produced has a polycrystalline structure with a dominant diffraction peak (101). Doping N into TiO2 affects the morphology of particle surface, thus tending to shrink. Results of photo catalysis on liquid samples of MB 20 ppm dye indicate that the addition of N improves the degradation ability of TiO2, with the highest value on sample T5 of 85% and with a rate of degradation kinetics of 0.024 ppm/minute.
