Pollutant Decomposition in Micro Porous Ceramics Made Out of Volcanic Rocks

Abstract:

Article Preview

Micro porous ceramics made out of volcanic rock have been considered as a pollution control material, since they show unique functional properties such as far infrared ray(IR) radiation, deodorization, anti bacterial function, and hygroscopic function. Here, it is well known that the ceramics have shown a mere adsorption function rather than the decomposition of absorbed substances. In an attempt to endow a sustained deodorization capability into the micro porous ceramics made out of volcanic rock, which has a normal pollution control function, TiO2 slurry as a photo catalyst was prepared and spray coated on the surface of the ceramics. Specific heat treatment has been performed at 200°C for 30 minutes after spray coating of TiO2 slurry and the subsequent deodorization properties were evaluated using the standard gas-bag method, which was established by Korea Photo catalyst Association and Japan Photo catalyst Association.
