volume are formed from initial C-nanotubes (table). It is interesting that phase of vanadyl
dihydrophosphate VO(H 2 PO 4 ) 2 (DHPV) with P/V=2 is crystallized under 170°C whereas
phase of HPV with P/V=1 under 200°C. VPO-samples based on oxidized C-nanotubes have
weakly developed porous structure.

Thus we prepared: /i/ micro-, meso- and macroporous carbon materials and /ii/ supported
VPO-catalysts with active phase in nanodispersion state. These catalysts is perspective for
oxidation of n-butane and oxidative dehydrogenation of light hydrocarbon.
