Adsorption of water on mesoporous silica for heat management: effect of pore structure.
As a potential adsorbent for humidity control, the mesoporous silica, SBA-15, with various pore sizes that was synthesized hydrothermally at different temperatures was examined by measuring the rate of water adsorption under ambient condition, 2.53 kPa H2O and 30 degrees C. The adsorption saturation quantity and the diffusion coefficient of water were changed consistently with the micropore fraction in SBA-15 obtained from the t-plot method. The diffusion of water into the SBA-15 was very similar to that on either zeolite A or Y because of the presence of complimentary pore.
