Wavelength dependence of the efficiency of photocatalytic processes for water treatment

M Martin-Somer, B Vega, C Pablos… - Applied Catalysis B …, 2018 - Elsevier
The main objective of this work is to present a novel approach to evaluate quantitatively the
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 …
