Abstract
Disclosed are catalysts capable of catalyzing the dry reforming of methane. The catalysts have a core-shell structure with the shell surrounding the core. The shell has a redox-metal oxide phase that includes a metal dopant incorporated into the lattice framework of the redox-metal oxide phase. An active metal(s) is deposited on the surface of the shell.
Claims20
A catalyst comprising a core-shell structure having:
- a metal oxide core, a clay core, or a zeolite core;
- a shell completely surrounding the core, wherein the shell has a redox-metal phase having tin (Sn), niobium (Nb), lanthanum (La), bismuth (Bi), indium (In) or gallium (Ga), or any combination thereof incorporated into the lattice framework of the redox-metal oxide phase;
- and
- an active-metal deposited on the surface of the shell, wherein the redox-metal oxide phase is cerium oxide (CeO2),
- wherein the catalyst is capable of catalyzing the production of hydrogen (H2) and carbon monoxide (CO) from methane (CH4) and carbon dioxide (CO2).
