Alkane dehydrogenation catalyst and methods of converting alkanes to alkenes

An alkane dehydrogenation catalyst, comprising:

• a catalyst support infiltrated with a plurality of catalytic nanoparticles, and;
• an atomic layer deposition overcoat;
• wherein the plurality of catalytic nanoparticles have an average size of about 0.6 nm to about 1.2 nm, the atomic layer deposition overcoat has a thickness of about 1.2 Å to about 1.2 nm, the catalyst support has a total surface area of 90 m2/g to 300 m2/g, a pore volume of 0.8 cm3/g to 0.4 cm3/g, and an average pore size of 6 nm to 17 nm.
