The Kinetics and Activation Energy of Photocatalytic Degradation of Phenol by TiO₂ and TiO₂/ PANI Photocatalyst under UV Irradiation

Abstract:

The kinetics and activation energy of photocatalytic degradation of phenol has been studied using the catalytically active TiO2 and PANI modified TiO2 nanoparticles. The reaction follows a pseudo-zero-order kinetics. Apparent activation energy of phenol photocatalytic degradation in water was 13.76kJ/mol by TiO2 and was 12.31kJ/mol by TiO2/PANI.
