This study reports the kinetics of the photocatalytic degradation of phenol using four different TiO2 catalysts. It is shown that phenol yields hydroquinone, catechol, benzoquinone and acetic and formic acids as main intermediate species. A phenomenological unified kinetic model (UKM) based in a “series-parallel” reaction network is proposed. The UKM follows a Langmuir-Hinshelwood kinetics with this being applicable to the various TiO2 photocatalysts studied. The UKM requires a number of significant assumptions in order to be used effectively avoiding overparametization. This approach also requires that the adsorption constants be obtained independently. As a result, the UKM is adapted for each …

Phenol degradation with TiO2 photocatalyst under UV light is known to be an effective method. Under solar radiation, however, this approach does not receive adequate photons for catalyst activation, as the solar spectrum comprises mostly visible light (46%). In this study, we applied the dye-sensitization technique to prepare visible-light-active catalyst and used it under visible solar light generated from a solar simulator with a UV cutoff filter (λ > 420 nm) for phenol degradation. Eosin Y dye was used as a sensitizer for the TiO2 catalyst with a very low level of platinum as a cocatalyst. Triethanolamine was used as a …


Photocatalytic Degradation Of Phenolic Compounds In Water: Irradiation And Kinetic Modeling, Jesus Moreira Del Rio Jan 2012

Photocatalytic Degradation Of Phenolic Compounds In Water: Irradiation And Kinetic Modeling, Jesus Moreira Del Rio

Scaling up a photoreactor requires both knowledge of optical properties of the slurry medium and an established kinetic model. Measuring the scattering and absorption coefficients of particles suspended in water involves the use of specialized optical equipment, as well as the partial solution of the radiative transfer equation (RTE). In addition, modeling of the radiation field in photoreactors with complicated geometries offers special challenges. On the other hand, most of the kinetic models (KM) for phenol photodegradation reported in the literature were obtained for a single organic chemical species only. In fact, neglecting all the intermediate species generated during the …
