Resumen:
The photocatalytic activity under UV, visible and UVvisible light of
two commercial catalysts for water remediation are evaluated in a slurry
reactor. Bisphenol A (BPA) is employed as the model pollutant. The activities
of the carbon-doped, TiO2 catalyst Kronos vlp 7000 and, as a
reference, the undoped catalyst Aeroxide
P25 are compared by means of the quantum efficiency parameter. Kronos
catalyst exhibits absorption in the visible range and was almost three times
more efficient than Aeroxide for BPA degradation under this condition. However,
under UV radiation, Aeroxide P25 quantum efficiency was about 1.5 times the
corresponding value of Kronos. Similar BPA efficiencies were obtained under
UVvisible radiation with both commercial catalysts.
