I want to calculate the BET results' mean pore size and volume!! Thank you!
To calculate the mean pore size and volume from Brunauer-Emmett-Teller (BET) results, you will need the following information: 1. BET surface area (S): This can be obtained from the BET analysis. 2. Amount of gas adsorbed at monolayer coverage (Nmon): This is the amount of gas adsorbed at a relative pressure close to 1, where the monolayer coverage is achieved. 3. Molecular weight of the adsorbate gas (M): This is the molecular weight of the gas used in the BET analysis. The mean pore size (D) can be calculated using the following equation: D = 4V/S where V is the volume of adsorbed gas at monolayer coverage. This volume can be calculated using the following equation: V = (Nmon x 22.414 x M) / (6.022 x 10^23) Note: The factor of 22.414 is used to convert from liters to cm3, and 6.022 x 10^23 is Avogadro's number. The mean pore volume (Vp) can be calculated using the following equation: Vp = V/Nmon where Nmon is the amount of gas adsorbed at monolayer coverage. By plugging in the values for S, Nmon, and M, you can calculate the mean pore size (D) and mean pore volume (Vp) from the BET results.
If you want to learn more about how you can calculate mean pore size,volume size, and distribution pore size, I have channel on youtube a its name dr.Angstrom.
