The effect of starting materials on the morphology and particle size of copper pyrovanadate Cu3V2O7(OH)2·2H2O

Copper pyrovanadate with spherical nanosize particles was successfully prepared from a mixture of vanadic acid solution and copper(I) oxide. Comparisons of X-ray diffraction profiles, scanning and transmission electron micrographs of particles of copper pyrovanadate obtained by using vanadic acid solution and xerogel of vanadium oxide solution were reported.
