Mesoporous metal carbides are of particular interest as catalysts for a variety of reactions because of their high surface areas, porous networks, nanosized walls, and unique electronic structures. In this work, two ordered mesoporous metal carbides, Mo2C and W2C, were synthesized using a nanocasting approach coupled with a simultaneous decomposition/carburization process under a continuous methane flow. The as-synthesized mesoporous Mo2C and W2C have three dimensionally ordered porous structures, large surface areas (70–90 m2 g–1), and crystalline walls. In vapor-phase anisole hydrodeoxygenation (HDO) reactions, they exhibited turnover frequencies of approximately 9 and 2 × 10–4 mol molCO–1 s–1, respectively, at relatively low reaction temperatures (423–443 K) and ambient hydrogen pressures. Notably, the ordered mesoporous W2C catalyst showed a greater than 96% benzene selectivity in anisole HDO, the highest benzene selectivity reported to date.
