Dry reforming of methane (DRM) is a promising method to utilize two greenhouse gases, such as CH4 and CO2, to produce synthesis gas. In the current work, both monometallic Ni and bimetallic Ni–Fe catalysts with different Fe/Ni molar ratios, synthesized by solution combustion synthesis (SCS) in DRM, were investigated using a feed ratio of CH4/CO2/Ar of 1:1:1 at 600–900 °C. The catalysts were characterized by several physicochemical techniques such as X-ray diffraction (XRD), scanning electron microscopy energy-dispersive X-ray (SEM-EDX) spectroscopy, transmission electron microscopy (TEM), CHNS, N2 physisorption, H2-TPR, O2-TPO, NH3-TPD, and thermogravimetric analysis (TGA). One of the highest hydrogen yields of 81% was obtained at 93% conversion of CH4 and 94% conversion of CO2 for the bimetallic 15Ni–5Fe–30Al catalyst, which contained, according to XRD, NiAl2O4 spinel and metallic Ni phases. The spinel phase was decomposed during the reaction, while the Ni3Fe alloy was formed. Catalysts with a higher Fe/Ni ratio exhibited lower conversion and contained an inactive FeAl2O4 spinel. Rather stable yields of CO and H2 were obtained in an experiment with 20 h time-on-stream.
