Abstract

FARIAS, Robson Fernandes de. Synthesis and characterization of a VOPO4-DMA compound. Quím. Nova [online]. 2003, vol.26, n.4, pp.493-496. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422003000400009.

A layered matrix, a-VOPO4.2H2O was used as host species to produce a VOPO4.dimethylacetamide intercalation compound. The oxovanadium matrix and the synthesized hybrid were characterized by elemental analysis, infrared spectroscopy, thermogravimetry, X-ray diffractometry and SEM microscopy. The X-ray diffraction patterns show that the VOPO4.dimethylacetamide compound is amorphous, but can be turned lamellar after a solubilization-crystallization process. The SEM micrographs obtained for the VOPO4-dimethylacetamide hybrid matrix show that the microstructure of VOPO4.2H2O is changed after reaction, with a delamination of the oxovanadium matrix.

Keywords : oxovanadium phosphate; intercalation compounds; amides.
