Application of TiO2 Nanoparticles in Clay Roofing Tiles as a Photocatalytic Active Material

A novel roofing tile was developed containing various types of nanoparticles of titanium dioxide (TiO2). Experiments were conducted using three types of TiO2 nanoparticles with and without polyethylene glycol (PEG). All types of newly developed nanomaterials were characterized using X-ray diffractometry. Particle size distribution analysis was performed and specific surface area was determined using the Brunauer–Emmet–Teller method. SEM imaging was used for the morphological characterization of nanoparticles. Commercial ceramic roofing tiles underwent a dip-coating procedure to obtain the desired photocatalytic surface. The TiO2 anatase samples exhibited greater surface areas of nanoparticles, thus providing potentially the highest photocatalytic efficiency.
