MUESES, Miguel A y MACHUCA-MARTINEZ, Fiderman. Mathematical Model for Non-Intrinsic Photonic Yields in Heterogeneous Photocatalytic Reactions. Inf. tecnol. [online]. 2012, vol.23, n.3, pp.43-50. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642012000300006.
A semi-empirical model was formulated to estimate the photonic efficiency of photocatalytic reactions in heterogeneous systems. This is a function of a pre-exponential factor called intrinsic photonic-efficiency and an exponential factor that quantified the effect of catalyst loading, geometry, and initial concentration of substrate. The assumptions and the model were validated on the photodegradation of dichloroacetic acid in three lab-scale heterogeneous photocatalytic reactors, using TiO2-P25 and low energy monochromatic radiation. It was found that the model is highly predictive for photonic efficiencies with relative errors below 1.8%.
