XRD and CO2 adsorption studies of modified silica gel with octadecylamine

Porous surface of silica gel (SG) have been modified with long and straight chain fatty amine compounds (octadecylamine, ODA) via wet impregnation process. Initially, heat treatment with various temperature which are 100 ºC, 200 ºC, 400 ºC and 600 ºC was done to the SG before continuing with impregn...
