The kinetics and activation energy of photocatalytic degradation of phenol by TiO_2 and TiO_2/ PANI photocatalyst under UV irradiation

摘要

The kinetics and activation energy of photocatalytic degradation of phenol has been studied using the catalytically active TiO_2 and PANI modified TiO_2 nanoparticles. The reaction follows a pseudo-zero-order kinetics. Apparent activation energy of phenol photocatalytic degradation in water was 13.76kJ/mol by TiO_2 and was 12.3 1kJ/mol by TiO_2/PANI.
