Firmly Adsorbed Ammonia and Pyridine Species at Activated Kaolinite Surfaces
Acid activation increases the protonated species on a kaolinite surface at the expense of coordinately bound NH 3 entities. The presence of NH + 4 ions on an activated sample is not proof of the presence of protonic acid centres alone since the added proton may have come from the residual water in t...
