Deodorization of natural zeolites have been improved not only for polar but also for non-polar pollutants by sucessive ion exchanges of H and Ag ions starting from Korean natural zeolite with high adsorption capacity. The modified zeolites with coating on the surface revealed high deodorization and photocatalytic decomposition effects. Further modification was made with silica nano particles coating on the surface, the resulting composite particles of natural zeolite revealed not only comparable deodorization but also better durability and resisatnce to color change compared to the /modified natural zeolite without much compensation of photocatalytic decomposition effect, when the composite particles were exposed to the polypropylene non-woven fiber coated with organic binder. It is expected for the composite particle prepared here to be used as indoor building materials for indoor air quality control.
