Abstract

A new vanadium zeolite labelled Nu-15 was prepared. The preparation procedure consists in hydrothermal decomposition of a vanadium glass for 4-10 days at 120-160 °C and saturated vapour pressure in a strongly basic solution of sodium hydroxide. The composition of the starting glasses was 15-17% Na₂O, 15-17% Al₂O₃, 25-40% SiO₂ and 30-45% V₂O₅, the composition of the zeolite, apart from water, corresponds to the formula 2 Na₂O.2 Al₂O₃.6 SiO₂.V₂O₅.
