Synthesis of Ni-Co/Al2O3-MgO Nanocatalyst via Impregnation Method Used in Hydrogen Production via Dry Reforming of Methane

In this study, Ni-Co/Al2O3-MgO nanocatalysts with two Al/Mg ratios of 0.5 and 5 were synthesized successfully using the impregnation method. The synthesized nanocatalysts were characterized by XRD, FESEM, BET, and FT-IR. The Ni-Co/Al2O3-MgO (Al/Mg=5) nanocatalyst showed high activity among other samples, which is due to its desired textural properties. XRD analysis illustrated that the Ni-Co/Al2O3-MgO (Al/Mg=5) nanocatalyst has smaller and well-dispersed NiO crystals. Also, the Ni-Co/Al2O3-MgO (Al/Mg=5) nanocatalyst due to BET analysis has a high specific area. According to the FESEM images, nanoscale particles with uniform surface size distribution have been observed in the Ni-Co/Al2O3-MgO (Al/Mg=5) nanocatalyst. During the 600 min stability test, feed conversion, and H2/CO molar ratio remained at constant values for the superior nanocatalyst.
