Ab initio predictions for elementary adsorption and reaction steps in heterogeneous catalysis

Experimental kinetic studies deal with complex reaction networks, whereas computational studies can provide energy barriers, reaction energies and pre-exponentials for individual reaction and adsorption steps. If made with sufficient, i.e. chemical, accuracy, computational predictions are very useful to check critical steps in microkinetic models. This we demonstrate for hydrocarbon activation by acidic zeolites, in particular proton exchange and cracking of alkanes as well as the formation of Ï€-complexes, alkoxides, and carbenium ions from alkenes. For the oxidative coupling of methane on Li-doped MgO this has lead to a revision of the well-established Lunsford mechanism.
