Summary
On the basis of theoretical calculations a procedure was developed which permits the production of highly reactive CaO surface states on MgO as support. Chemical Vapour Deposition (CVD) provides nanostructured particles of MgO/CaO mixed oxides. They are subjected to an appropriate thermal treatment, which initiates Ca2+ segregation into the surface. This gives rise to a significant thermal stability of the oxide particles and creates highly reactive surface centres which tend to chemisorb methane already at room temperature.
