Water Adsorption on Kaolinite Surfaces Containing …

 · Recent laboratory studies of water adsorption on kaolinite at 296 K, and at relative humidity (RH) values relevant for the atmosphere, have reported coverages ranging up to tens of monolayers. In contrast, recent simulations have suggested that atomistically smooth kaolinite surfaces uptake only monolayers (some slightly overgrown) at similar RH values. In an effort to possibly explain the ...
