Amine grafting on MCM-41
Characterization of the materials prepared
CO2 adsorption-desorption measurement
Al(i-PrO)3 (41.68g)+ Alcohol solvent
(EtOH 73.6g + isopropanol 72.2g) at 50oC
Distilled water (7.2g) – promote hydrolysis
Stirring – 9 hr at room temp
Heat (sol)- 70oC for 24 hr in oven
Heat (gel)- 120oC for 12 hr in autoclave
Washing with EtOH and drying
The Barrett-Joyner-Halenda (BJH) method for calculating pore size distributions is based on a model of the adsorbent as a collection of cylindrical pores. The theory accounts for capillary condensation in the pores using the classical Kelvin equation, which in turn assumes a hemispherical liquid-vapor meniscus and a well-defined surface tension.
