1. A method of dry reforming methane, comprising reacting the methane with carbon dioxide via a reforming catalyst at a temperature of 700-900° C. and a pressure of 7 bar to 14 bar to generate synthesis gas comprising hydrogen and carbon monoxide, wherein the reforming catalyst comprises:
19.5 wt % of a nickel component;
0.5 wt % of a ruthenium component;
and
80 wt % of a cerium and gadolinium oxide component.
