Ultimately, however, DFT calculations suggest that while coke formation on the Pt4Ge system is not avoided, the cluster nonetheless retains its active and selective nature towards alkane dehydrogenation. Thus, the conclusion is that selectively-coked Pt4GeC2/alumina, generated under reaction conditions by a self-limiting coking process, is the actual stable, active, and selective catalyst for alkane-to-alkene dehydrogenation.
