Cobalt-Based Single-Atom Dehydrogenation Catalysts and Method for Producing Corresponding Olefins from Paraffins Using the Same

A dehydrogenation catalyst that is a cobalt-based single-atom catalyst comprising:

• silica having an alkali metal adsorbed thereon as a support;
• and
• cobalt, as an active metal, loaded on the support,
• wherein the cobalt having an oxidation number of 2+ and the alkali metal having an oxidation number of 1+, respectively, exist in an isolated form of single atom on the silica while the cobalt having an oxidation number of 2+ forms a tetrahedrally coordinated at the three-membered siloxane ring present on the surface of silica.
