非晶高表面积钒铝氮氧化物（VAION）的非晶氧化物前体的氮化制备表现出很高的丙烯腈产率在丙烷氨氧化在非常低的接触时间，表明氨脱氢物种的参与烷烃的氨氧化。与已知的氧化物体系相比，VAlON催化剂的产率（l ACN/kg催化剂/h）显著提高。
Amorphous high-surface-area vanadium aluminum oxynitrides (VAlON) prepared by nitridation of an amorphous oxide precursor exhibit a high acrylonitrile yield in propane ammoxidation at very low contact time, indicating the participation of ammonia dehydrogenated species in the ammoxidation of alkanes. The productivity of the VAlON catalysts (l of ACN/kg catalyst/h) was markedly improved as compared with known oxide systems.
