Subsurface nickel boosts the low-temperature performance of a boron oxide overlayer in propane oxidative dehydrogenation

Abstract

The working temperature of boron-based catalysts reduces their thermodynamic advantages in the oxidative dehydrogenation of propane (ODHP). Here the authors demonstrate encapsulated Ni nanoparticles as effective subsurface promoters to enhance the low temperature activity and selectivity of the boron oxide overlayer in ODHP.
