The Ni−Cu/MgO.Al2O3 catalyst with large BET surface area (>126 m2/g) was successfully synthesized by facile simultaneous sol-gel method (SSGM) route in the absent of surfactants and propylene oxide (C3H6O) was employed as gelation agent. The praperd catalysts were adopted for thermocatalytic dehydrogenation of methane to highly pure hydrogen. After that, the catalytic performance and structural properties of the different nominal loadings palladium (2, 4 and 6 wt.%) promoted Ni-Cu/MgO.Al2O3 (Sol.) were evaluated. The results showed that the addition of Pd can significantly promote the catalytic activity and stability. The physicochemical properties including textural properties of the prepared catalysts were investigated using different analytical methods such as BET and TEM techniques. N2 adsorption-desorption isotherms and BET analysis revealed mesoporous structure with BET surface area in the range of ~94- 126 m2/g. Among the prepared samples studied, 4 wt.% of palladium sample showed optimal catalytic performance and stability at higher temperatures towards methane thermocatalytic decomposition
