Abstract
Tandem catalysts for the dehydrogenation of alkanes and/or alcohols in tandem with selective hydrogen combustion are provided. Also provided are methods of making the catalysts and methods of using the catalysis for the dehydrogenation of alkanes and/or alcohols. The catalysts include a support having a surface, dehydrogenation catalysts particles dispersed on the surface of the support, and a porous selective hydrogen combustion catalyst overcoat on the dehydration catalyst particles. The catalysts couple dehydrogenation with selective hydrogen combustion in a sequence of reactions occurring in tandem to shift the equilibrium of the dehydrogenation towards higher conversion.
