The kinetics and activation energy of photocatalytic degradation of phenol by TiO2 and TiO2/PANI photocatalyst under UV irradiation

摘要

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 12.31 kJ/mol by TiO2/PANI.
