Abstract

The use of Polypropylene as support material for nano-TiO2 photocatalyst in the photodegradation of several dyes in water solutions under the action of Visible light was investigated. The optimization of TiO2 pastes preparation using two commercial TiO2 has been performed and green, low-cost dip-coating procedure was developed. Scan electron microscopy and Atomic Force Microscopy were used in order to obtain morphological information of TiO2 on support material. Equilibrium and kinetic aspects in the adsorption and photodegradation of Methylorange and Alizarin Red S are described using polypropylene-TiO2 films in the Visible/TiO2/air reactor showing efficient dyes degradation.
