Isosynthesis process in the presence of a catalyst based on an oxide of at least two different metals, having a specific surface of at least 20 m2 / g and a structure of cubic type, perovskite, garnet, ilmenite, fluorite or related to the fluorite type, said oxide being in particular prepared by a process comprising in particular a final stage of calcination of a gel containing said metals. Said oxide thus prepared has a substantially zero reactivity with respect to water and carbon dioxide. |
