It highlights the importance of techniques such as Secondary Electron Microscopy (SEM) for topography and Scanning Auger Microscopy (SAM) for compositional analysis.

It contrasts physisorption, which involves weak van der Waals forces, with chemisorption, characterized by stronger chemical bonds. The text outlines the adsorption process of hydrogen molecules (H2), discussing two pathways: direct chemisorption and precursor-mediated chemisorption, which includes initial physisorption.

Few, if any surfaces are perfectly flat, and thus the cavities, protrusions, ridges, and edges of the surface must be treated differently when studying chemisorption and physisorption.
