Synergetic Effects Leading to Coke-Resistant NiCo Bimetallic Catalysts for Dry Reforming of Methane

A new dry reforming of methane catalyst comprised of NiCo bimetallic nanoparticles and a Mgx(Al)O support that exhibits high coke resistance and long‐term on‐stream stability is reported. The structural characterization by XRD, TEM, temperature‐programmed reduction, and BET analysis demonstrates that the excellent performance of this catalyst is ascribed to the synergy of various parameters, including metal‐nanoparticle size, metal–support interaction, catalyst structure, ensemble size, and alloy effects. Synergetic effect: A coke‐resistant and long‐term stable dry reforming of methane catalyst comprised of NiCo bimetallic nanoparticles and a Mgx(Al)O support is reported. Diverse parameters, including metal‐nanoparticle size, strong metal–support interaction, catalyst structure, ensemble size, and alloy effect are demonstrated to work cooperatively and lead to the excellent catalytic performance of the catalyst.
