CERAMIC CATALYST HAVING IMPROVED ABSORPTION AND DISINTEGRATION PROPERTIES FOR VAPOR PHASE COMPOUNDS AND PREPARATION METHOD THEREOF

摘要

Disclosed are a ceramic catalyst containing a metal oxide having absorption and disintegration properties for vapor phase compounds prepared from a porous ceramic material, water-soluble metal salt, and optionally a combustible material, and a preparation method thereof comprising the step of mixing a porous ceramic material with a water-soluble metal salt and firing to a metal oxide generated from the metal salt uniformly dispersed in a ceramic material. The ceramic catalyst can absorb and disintegrate vapor phase composition even at a low temperature of lower than 100 ° C, especially, at an ordinary room temperature of approximately 25 °C, without light assistance .
