Enhanced coking resistance of alumina-supported cobalt nitride catalyst via doping of phosphorus for dry reforming of methane

Abstract

A novel P-doped Co₄N/γ-Al₂O₃ catalyst was firstly designed for dry reforming of methane (DRM). It was found that the use of P doping Co₄N/γ-Al₂O₃ can enhance its coking resistance, which might be due to a decrease in CH₄ dissociation ability and an increase in CO₂ dissociation ability, as well as the increase of cobalt species capable of interacting with alumina.
