Novel preparation of vanadyl pyrophosphate for selective oxidation of n-butane utilizing intercalation and exfoliation
Intercalation-exfoliation of VOPO4. 2H(2)O crystallites (20 I-lm in size) in 2-butanol, followed by reduction with 2-butanol, brought about thin layers of precursor, VOHPO4.0.5H(2)O, with size of about 2 mum. The obtained vanadyl pyrophosphate (27 m(2) g(-1)) and the corresponding SiO2 composite were highly active and selective for selective oxidation of n-butane.
