Description:

Humidity-controlled materials that maintain a comfortable indoor environment must have both high water vapor-adsorption properties under high humidity and appropriate water vapor-releasing properties with the relative humidity of 40%–70%. Such properties are often observed in mesoporous materials but are generally absent in microporous zeolites. Previously reported bulk zeolite bodies with mesopores and interconnected macropores were characterized using mercury porosity and water–vapor adsorption/desorption measurements. The bulk material comprised bottleneck-shaped pores and had a humidity-control function that was not exhibited by conventional zeolite materials. Therefore, bulk zeolites have demonstrated potential as excellent humidity-controlled materials with the function of volatile organic compounds removal owing to their micropores.
