摘要：Nickel catalysts catalyzing the DRM reaction have the problems of sintering and coking. Herein we proposed an idea of stabilizing nickel by Ni17W3 alloy, and alpha-WC formed during the DRM reaction participated in the CO2 activation, leading to a better coke resistance of Ni17W3/SiO2 catalyst. Due to better Ni dispersion and less coke deposition, Ni17W3/SiO2 catalyst exhibits an improved catalytic stability for the DRM reaction compared with the model Ni/SiO2 catalyst.
