By a News Reporter-Staff News Editor at Journal of Mathematics -- Investigators publish new report on Photocatalytics. According to news reporting originating in Brisbane, Australia, by VerticalNews journalists, research stated, "The use of immobilised TiO2 for the purification of polluted water streams introduces the necessity to evaluate the effect of mechanisms such as the transport of pollutants from the bulk of the liquid to the catalyst surface and the transport phenomena inside the porous film. Experimental results of the effects of film thickness on the observed reaction rate for both liquid-side and support-side illumination are here compared with the predictions of a one-dimensional mathematical model of the porous photocatalytic slab."
The news reporters obtained a quote from the research from the Queensland University of Technology, "Good agreement was observed between the experimentally obtained photodegradation of phenol and its by-products, and the corresponding model predictions. The results have confirmed that an optimal catalyst thickness exists and, for the films employed here, is 5 mu m. Furthermore, the modelling results have highlighted the fact that porosity, together with the intrinsic reaction kinetics are the parameters controlling the photocatalytic activity of the film."
According to the news reporters, the research concluded: "The former by influencing transport phenomena and light absorption characteristics, the latter by naturally dictating the rate of reaction."
