A facile one-step synthesis of molybdenum carbide-carbon composites for the hydrogenation of naphthalene.

A molybdenum carbide-carbon composite (β-Mo2C/C) is prepared by carbonization of an anionic resin with molybdate. The β-Mo2C/C is characterized by X-ray diffraction, N2 physisorption, scanning electron microscopy, and transmission electron microscopy. Characterization indicates that the sample shows a hierarchically microporous, mesoporous, and macroporous structure, and has a large surface area. The nanosized β-Mo2C crystals are highly dispersed in the carbon-based sample. The β-Mo2C/C composite shows high catalytic activity in the hydrogenation of naphthalene to tetralin.
