Abstract

This study utilized the Gas in Scattering Media Absorption Spectroscopy (GASMAS) technique to examine the diffusion dynamics of water vapor in commercial mesoporous silica MCM-41 and SBA-15. The GASMAS technique employed an innovative semiconductor laser configuration, utilizing a tunable diode laser at 936 nm to facilitate real-time monitoring of water vapor absorption. This approach is straightforward and economical, yielding localized insights into diffusion behavior. Our findings indicate a notably slow time constant rate, influenced by hydrogen bonding interactions with pore walls, size, and relative humidity.
