Molybdenum Carbide Microcrystals: Efficient and Stable Catalyst for Photocatalytic H₂ Evolution From Water in The Presence Of Dye Sensitizer

Rod-like molybdenum carbide (Mo₂C) microcrystals were obtained from the pyrolysis of Mo-containing organic-inorganic hybrid composite. We investigated the photocatalytic H₂ evolution activity of Mo₂C by constructing a Mo₂C-dye sensitizer photocatalyst system. A high quantum efficiency of 29.7% was obtained at 480 nm. Moreover, Mo₂C catalyst can be easily recycled by simple filtration.
