In the present work it is shown how geopolymers can be used to control indoor and outdoor air pollution by photolysis of 2-Butanone as a Volatile Organic Compound (VOC). An ion exchange procedure was followed to incorporate TiO2 into a geopolymer (IEG), and different 2-Butanone concentrations were used in a batch reactor under dry and humid conditions. Variation on 2-Butanone concentration was followed by gas chromatography. A Langmuir-Hinshelwood model was used to determine the disappearance rate of reactant at the initial stage of the reaction. © 2014 Elsevier B.V. Source
