Abstract: A metal carbide imbedded ordered mesoporous carbon (MC-OMC) material was synthesized by direct carbonization of a self-assembled composite that was made from F127 (EO₁₀₆PO₇₀EO₁₀₆), resorcinol-formaldehyde, and (NH₄)₆Mo₇O₂₄•4H₂O or (NH₄)₂WO₄ in an acidic medium of aqueous ethanol solutions. The type and amount of the metal ions have a great influence on ordering degree of the resulting materials. Metal carbide particles with uniform size of 3–5 nm are highly dispersed on the pore wall of the carbon structure. The prepared MoC-OMC has excellent activity for direct N2H4 decomposition. The strong interaction between Mo₇O₂₄^6– and the resin plays an important role in the synthesis of this material.
