Paper Abstract

The oxide ion conductor material, Cu doped Bi4V2O11 (BICUVOX.10) powders were prepared by the combined EDTA (ethylene diamine tetra acetic acid)-citrate synthesis technology. The dried gel was annealed at various temperatures (400-600°C). Powders derived from dried precursor resulted in the mixed phases to BiVO4 and high temperature γ-phase of Bi4V2O11 by heat-treating below 400°C, and furthermore, yielded only pure γ-phase above 500°C. A simple surfactant-stabilized method was investigated for the preparation of well-dispersed nanoparticles. It was found that the deagglomeration treatment to the precursor by surfactant polyethylene glycol (PEG) 4000 was effective in improving the size distribution and annealing conditions of the BICUVOX.10 material.
