Descripción
Titania nanoparticles (TiNPs) prepared by the sol?gel method have been incorporated to cement paste with the aim of creating a photocatalytic system capable of compensating, through degradation of hazardous molecules, the environmental impact associated to the production of the clinker. Doping was carried out at different mass ratios with TiNP precursor solutions within a fresh cement paste, which was then characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The photocatalytic performance was evaluated by the degradation of Methylene Blue (MB) using a 125W UV lamp as irradiating source. Main cement properties such as hydration degree and C-S-H content are affected by TiNP doping level. Cement containing TiNPs exhibited an increasing photocatalytic activity for increasing doping, while the pure cement paste control could hardly degrade MB. The kinetics of the system where also studied and their second order behavior related to microstructural aspects of the system.
