Abstract
A catalyst in ammonia synthesis includes a first layer of metal monochalcogenide-based material; a second layer of metal monochalcogenide-based material stacked with and is spaced from the first layer of metal monochalcogenide-based material by a first distance; wherein the metal monochalcogenide-based material includes SnS. A method of preparing the catalyst and an electrochemical ammonia synthesizing device making use of the catalyst thereof are also addressed.
Claims16
A catalyst in ammonia synthesis comprising:
- a first layer of metal monochalcogenide-based material;
- a second layer of metal monochalcogenide-based material stacked with and is spaced from the first layer of metal monochalcogenide-based material by a separation distance;
- wherein the metal monochalcogenide-based material includes SnS;
- the metal monochalcogenide-based material is doped by a lanthanide atom;
- the first and second layers of metal monochalcogenide-based material are intercalated by a metal intercalating atom that covalently bonds the first and second layers of metal monochalcogenide-based material at a bonding site, the metal intercalating atom being a transition metal atom.
