17 O NMR of the Structural Evolution of V 2O5 Gels.

Abstract

Recent studies of the synthesis of V2O5 gels by acidifying metavanadate salt solutions suggest that dioxovanadium cations polymerize into chains of vanadate octahedra. In this study we characterize the growth of vanadate polymers by both solution and MAS 17O NMR. The spectra are consistent with the formation of a chain polymer with a repeat unit of V sub OHO2(OH)(OH2)2. The 17O NMR spectra also suggest that the chains might connect to each other through the hydrogen bonding. (jg)
