摘要：

Vanadium-containing aluminophosphate five (VAPO-5) was synthesized and shown to contain vanadium species that cannot be removed by ion exchange. These vanadium species are primarily vanadyl like in the as-synthesized VAPO-5, but calcination in 500°C O2 converts most of the V4+ to V5+. Exposure to 500°C H2 and ambient moisture returns the V5+ to vanadyl. © 1990 American Chemical Society.
