Kinetics of Heterogeneous Photocatalytic Decomposition of Phenol over Anatase TiO2 Powder
TL;DR: In this paper, the photocatalytic decomposition of phenol over anatase TiO2 powder followed the first-order kinetics, upto high conversions, of which the apparent rate constant kap depended on initial concentration of the phenol [phenol]0, [TiO2], O2 pressure pO2, and incident light intensity I. The activation energy was 10 kJ/mol.
