Abstract
The CeO2–SiO2 nanocomposite was assembled by a new flame aerosol transport method. Dispersion of ultrafine ceria nanoparticles in a TEOS-methanol solution was used to obtain an aerosol serving as a transport medium for ultrafine ceria nanoparticles. The obtained CeO2–SiO2 coating embedded on an Al underlay was characterised in detail by optical microscopy, XRD, SEM and by EDS. The composite consisted of nano-sized ceria and an amorphous silica phase. Application of the obtained composite was demonstrated by testing of the catalytic properties of the ceria component on decomposition of 2,4,6 – TCP in water. It is apparent from the results that the composite can be used in various applications e.g. in environmental decontamination applications.
