Comparison of surface areas with electron microscopy

4 Comparison of surface areas with electron microscopy 

EM techniques provide important information in the characterization of the dispersion of metallic catalysts. Surface areas of catalysts are measured by the standard BET method described previously. An isotherm is produced using nitrogen as the adsorbate chemisorption of certain gases (e.g. H2 or CO) is also used, including for particle size distributions. We give some examples in chapter 5.
