Deposition and characterisation of TiO2 coatings on various supports for structured (photo)catalytic reactors

Abstract : Different types of aqueous TiO2-P25 suspensions were prepared and their properties, including rheological behaviour and zeta potential, were studied. Then, TiO2 suspensions were used to elaborate TiO2 coatings on various substrates (cordierite monolith, stainless steel plates and beta-SiC foam) using a dip-coating method. The relationship between the suspension stability and the coating adhesion has been considered. The structural and morphological characterisation of TiO2 coatings has been performed using scanning electron microscopy, X-ray diffraction and other methods. Finally, the photocatalytic properties of the materials have been determined by studying the photooxidation of aqueous ammonia.
