^a(% mol adsorbate/mol mg).

^bThe fraction of surface sites is given for particles exposing either (104)- or (110)-surface sites, see text.

^c35Cl intensities from solid-state NMR experiments are an average between magic-angle spinning (MAS) and static relative intensities, where the difference between MAS and static was never more than 3%.

^dSee ref (42).

^eThe average size could not be determined because the XRD resonances were too narrow (dry MgCl₂) or too broad (Do3_7).

^fNumbers in bold face indicate most probable exposed surface.
