Abstract
Disclosed are catalysts that include a doped atomic monolayer (e.g., graphene or hexagonal boron nitride) bonded to a nickel-based component. The dopant can be a transition metal or nonmetal dopant and the nickel-based component can be pure nickel (e.g., Ni(111)) or nickel/metal alloys. Also disclosed are processes for catalyzing reactions that include adsorbing a small molecule to the catalyst and contacting the adsorbed small molecule with a reactant. Catalyzed reactions include oxidation reactions including oxidation of methane to methanol, oxidation of carbon monoxide (e.g., in a PROX reaction).
Claims17
A method for oxidation of methane to form methanol comprising:
- adsorbing oxygen on a catalyst, wherein the oxygen is chemisorbed on the catalyst, the catalyst comprising an atomic monolayer comprising graphene or hexagonal boron nitride, the catalyst further comprising a transition metal single atom dopant in a lattice of the atomic monolayer, wherein the atomic monolayer is covalently bonded to a surface of a support, the support comprising nickel (111) at the surface;
- contacting the adsorbed oxygen with methane, upon which the methane is physisorbed on the catalyst and the methane is oxidized to form methanol.
