摘要

Abstract

The dry reforming of methane (DRM) reaction can directly convert methane (CH

) and carbon dioxide (CO

) into syngas (H

+CO)

which is a promising method for achieving carbon neutralization. In this study

a series of 3Ni-

Co/Mg

HAP alloy catalysts with different ratio were synthesized by the coprecipitation method

and the optimum Ni-Co ratio for the DRM reaction was studied. A series of characterization methods revealed that after Co was added

the formation of Ni-Co alloys increased the interactions between metals. However

an excess of Co inhibits the entry of Ni into the lattice of Mg

HAP

resulting in metal accumulation on the surface of the support. In addition

the introduction of Co improves the dispersion of Ni metal

which endows the catalyst with better catalytic activity and stability. Raman spectroscopy of the catalyst after the stability test showed that the addition of Co reduced the proportion of graphitic carbon

which was also the main reason for its improved stability.
