Catalytically active Ni metal particles were generated upon thermal treatment of Ni-MOF-74 (acting as a precursor), while Mg-MOF-74 functions as a stable catalyst support with a high CO₂ adsorption capacity. The resulting 50Ni50Mg-MOF-74-derived catalyst exhibited superior performance in CO₂ hydrogenation to CH₄ at 350 °C compared to catalysts derived solely from Ni-MOF-74. The thermal stability of Mg-MOF-74 was confirmed through X-ray diffraction and TG-DTA, while the formation of well-dispersed Ni metal particles was shown by transmission electron microscopy and HAADF-STEM measurements.
