摘要

The co-ammonolysis of V(NMe2)(4) and Si(NHMe)(4) with ammonia in THF and in the presence of ammonium triflate ([NH4][CF3SO3]) leads to the formation of monolithic gels. Pyrolysing these gels produces mesoporous composite materials containing nanocrystalline VN and amorphous silicon imidonitride. Elemental mapping indicated a thorough distribution of VN with no evidence of large cluster segregation. Whilst not active for ammonia synthesis, the silicon nitride based materials were found to possess activity for the COx-free production of H-2 from methane, which makes them candidates for applications in which the presence of low levels of CO in H-2 feedstreams is detrimental.
