Electrochemical and Photocatalytic Decomposition of Perfluorooctanoic Acid with a Hybrid Reactor Using a Boron-doped Diamond Electrode and TiO2 Photocatalyst
The efficient decomposition of environmentally persistent perfluorooctanoic acid (PFOA) was achieved by a hybrid of electrolysis and photocatalysis. The rate constant of PFOA decomposition in the hybrid system was larger than the sum of the constants in electrolysis-only and photocatalysis-only systems. The hybrid system was able to accelerate the PFOA decomposition by complementally support of two kinds of reaction kinetics. These results could be useful for development of a new continuous system for practical treatment of waste water containing perfluorinated acids.
