The role of Co-Ga₂O₃ interfaces in methane dry reforming.

ABSTRACT: As the combination of Co with other non-noble metals is a viable way to improve the catalytic properties of Co in methane dry reforming (DRM), we studied an impregnated Co₃O₄/β-Ga₂O₃ powder catalyst to understand the influence of Ga and the catalytic role of the Co-Ga₂O₃ interface and the intermetallic compound CoGa in DRM. Co₃O₄/β-Ga₂O₃ undergoes a series of structural transformations during activation by reduction in hydrogen and under DRM conditions. Contact to the CO₂/CH₄ mixture without hydrogen pre-reduction yields CoGa₂O₄ spinel particles encrusting β-Ga₂O₃ without significant DRM activity. Hydrogen reduction
