Effects of weathering on the performance of self-cleaning photocatalytic paints

2019

Abstract The use of photocatalytic products for the surface coating of buildings is spreading more and more, because of the reduction of atmospheric pollutants and the colour maintenance of the paints over time with reduction of the maintenance costs and the improvement of the aesthetic appearance. The study reports the evaluation of the effects of the atmospheric conditions on three commercial photocatalytic paints containing TiO2. In particular tests were carried out by using samples subjected to accelerated aging inside a climate chamber and naturally aged by exposure for two years to the external environment of the city of Palermo (representative of a coastal environment of the Mediterr…

TiO2-CeO2 based catalysts for photocatalytic oxidation of VOC and water splitting reactions

2016

Photocatalysis with TiO2 is one of the most promising green process for the decomposition of organic pollutants and the hydrogen production . Photo-oxidation of 2-propanol, representative of volatile organic compounds (VOC) and photo-catalytic water splitting for H2 production were investigated over TiO2 catalysts doped with a metal (Au and Ag at 1wt. %) and/or ceria (10 wt.%).
