Abstract A new method has been developed for the deoxygenation of vanillin to produce 2‐methoxy‐4‐methylphenol (MMP) as a promising liquid fuel over heterogeneous non‐noble metal catalyst. Cobalt nanoparticles supported on nitrogen‐doped carbon (Co/N‐C‐600) exhibit high activity and stability into MMP under mild conditions (150 °C, 10 bar H 2 ). Nearly quantitative yield is obtained in isopropanol after 8 h at 150 °C pressure. According distribution products with time, mainly proceeds through hydrogenation vanillyl alcohol subsequent hydrogenolysis MMP, which latter rate‐determining step, owing much higher activation energy. Moreover, being recycled several times, loss catalytic negligible, demonstrates that Co/N‐C‐600 catalyst shows good resistance deactivation.
