Cathy Miller(ICL)June 2002:
N2 adsorption (physisorption) has been used to find the BET surface areas of high surface area materials such as mesoporous silicas (MCM-41, MCM-48, SBA-15) and to investigate the effect of grafting organic/organometallic/inorganic species onto the surface of the material (which generally lowers the surface area). The instrument has also been used to characterise these materials by using data processing software to calculate pore size distributions, adsorption isotherms and BET plots.
In addition, N2 physisorption has been used to measure the change in surface area of microporous materials on removal of the template molecules necessary for their formation.
H2 chemisorption experiments have been carried out on some samples used for Fischer-Tropsch catalysis, consisting of Ni and Mo dispersed on silica. These can be used to determine the number of active metal centers on the surface and their dispersal.
