Deactivation due to coking and sintering are still major problems that restrain the durability and performance of commercial Pt-based heterogeneous catalysts. Even small improvements in the selectivity of alkane dehydrogenation represent significant energy and economic savings. There is thus a great incentive to mitigate coking and sintering to enhance the catalyst lifetime, and in particular improve the stability of subnano clusters to make them industrially practicable.
