Description
Summary:[Display omitted] •Nitrogen doped carbon improved the activity of Fe based catalyst in propane dehydrogenation.•With modification, highly dispersed and electron-rich Fe species were formed.•The modification strategy was validated for the catalysts with different supports and precursors. 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.
