摘要
The structure of photocatalytic and photoluminescent binary vanadate of the general formula "CaZnV2O7" has been investigated using X-ray powder diffraction. The compound is built up of isolated [V3O10], and [VO4] being this complex trivanadate-vanadate, in opposition to previous suggestions on isostructurality "CaMV2O7", M - Mg or Co (Murashova et al., 1991, 36, 617-621). The present model has been confirmed by theoretical calculations. Thermal analysis and scanning electron microscopy have been performed, and the electronic structure analysis has been found to be in agreement with the experimental observations.
