Abstract: A method is disclosed for producing photocatalytic coated ceramic granules. The method involves providing a coatable composition containing an inorganic binder and a variety of photocatalytic particles, such as TiO2, ZnO, Ti(OH)4, doped derivatives, or combinations thereof. These photocatalytic particles have a surface area per weight of no more than 15 m2/g. The coatable composition is then applied to uncoated base ceramic granules, resulting in intermediate coated granules. Finally, the intermediate coated granules are heated at a temperature of at least 700° C., leading to the formation of photocatalytic coated ceramic granules. These granules exhibit a Total Solar Reflectance (TSR) value of at least 0.7. This method offers an efficient and effective way to produce ceramic granules with enhanced photocatalytic properties.
