Catalytic ammonolytic sol-gel preparation of a mesoporous silicon aluminium nitride from a single-source precursor

ORTEP plot of the structure of the precursor molecule tetrakis(isopropylimino)bis[tris(dimethylamino)silylamino]alane H6Al6(NiPr)4[NSi(NMe2)3]2 for the sol-gel preparation of an amorphous Si-Al-N ceramic composite via a microporous silicon aluminum imide gel. The ceramic composite is mesoporous (2-8 nm) with a relatively high surface area (114 m2 g−1).
