Fabrication of a highly stable Ni–Co bimetallic catalyst for the steam reforming of methane via in situ crystallization of phyllosilicate on porous spherical silica

Ni–Co bimetallic nanoparticles as catalysts for the steam reforming of methane were dispersed on mesoporous silica spheres by aging an aqueous alkaline suspension of silica at 150 °C in the presence of Ni 2+ and Co 2+ , followed by H 2 reduction.
