action spectra and energy efficiency for chemical oxidation and bacterial inactivation of
photocatalytic processes using monochromatic LED sources. Two different catalysts with
different absorption spectra (TiO 2 and iron citrate complex) were used. In all cases, it was
confirmed a direct relationship between the absorption spectrum of the catalyst and the
spectral dependence of the photonic efficiency. The best alternative for TiO 2 processes in …
