Abstract (en)

[origin: FR2760979A1] The invention concerns a catalyst with modified molybdenum oxycarbide base having a specific surface area more than 5 m<2>/g and improved catalytic activity, in particular in velocity constant, characterised in that it is prepared from molybdenum oxide MoO3 with a structure essentially comprising preferentially oriented monocrystalline plates resulting from sublimation condensation. The invention also concerns a method for producing such a catalyst.
