Efficient Fe based catalyst with nitrogen doped carbon material modification for propane non-oxidative dehydrogenation

Nitrogen doped carbon species (NC) was introduced into Fe based catalyst and applied into propane non-oxidative dehydrogenation. With characterizations of XRD, TEM and XPS, it was deduced that the NC modification induces the electrons transferred from NC species to Fe species, leading to electron-rich Fe species. Consequently, propane conversion and propene selectivity were increased by suppressing the by-products formation. It was also confirmed that such a modification strategy could be also extended to ones with different supports, iron precursors, and NC precursors.
