REPORT


ABSTRACT Diamine vanadium oxide nanotubes (DA-VOx-NTs) have been prepared in high yields applying two different synthesis routes, namely either a sol-gel reaction followed by a hydrothermal treatment or an exchange reaction. The first route is analogous to the well-known preparation of VO,-NTs containing monoamines: a vanadium(V) alkoxide is mixed with an cL,o)diamine (H2 N[CH 2]nNH 2 with 12
