Porous metal oxide materials, useful for removing water in air conditioning plant, e.g. for vehicle, have water vapor adsorption capacity varying with relative water vapor pressure

摘要

Porous material (A) comprises a metal oxide skeleton and has a water vapor adsorption capacity = 0.1 g/l at 10% relative water vapor pressure (RH) and - 0.2 g/l at 28% RH. Independent claims are also included for (a) various porous materials with a metal oxide skeleton and different water vapor adsorption capacities at different RH values; (b) methods of preparing porous materials.
