Mechanism of photo catalytic degradation of Brilliant Blue colorant in water suspension with TiO2 catalyst

Water purification by photo catalytic decomposition of Brilliant Blue colorant in water suspension was studied. This work presents experimental and theoretical results in which the mechanism is discussed of decomposition of an organic colorant’s molecule. In theoretical part, a calculation of the energy levels of the molecule and its parts derived in decomposition process based on modified FEMO modeling confirm the mechanism proposed (© 2011 WILEY-VCH Verlag GmbH & Co.
