Ni‐Co Bimetallic Catalysts Supported on Mixed Oxides (Sc‐Ce‐Zr) for Enhanced Methane Dry Reforming
Abstract Dry methane reforming (DRM) presents a viable pathway for converting greenhouse gases into useful syngas. Nevertheless, the procedure requires robust and reasonably priced catalysts. This study explored using cost‐effective cobalt and nickel combined into a single catalyst with different me...

| description | Abstract Dry methane reforming (DRM) presents a viable pathway for converting greenhouse gases into useful syngas. Nevertheless, the procedure requires robust and reasonably priced catalysts. This study explored using cost‐effective cobalt and nickel combined into a single catalyst with different metal ratios. The reaction was conducted in a fixed reactor at 700 °C. The findings indicate that the incorporation of cobalt significantly enhances catalyst performance by preventing metal sintering, improving metal dispersion, and promoting beneficial metal‐support interactions. The best‐performing catalyst (3.75Ni+1.25Co‐ScCeZr) achieved a good conversion rate of CH4 and CO2 at 46.8 %, and 60 % respectively after 330 minutes while maintaining good stability. The TGA and CO2‐TPD analysis results show that the addition of Co to Ni reduces carbon formation, and increases the amount of strong basic sites and isolated O2− species, and the total amount of CO2 desorbed. These results collectively highlight the potential of cobalt‐nickel catalysts for practical DRM applications and contribute to developing sustainable energy technologies. |
