The paper describes the preparation and characterization of nano-size metastable tetragonal CeO2–ZrO2 mixed oxides prepared by a polymerized complex method. A glycine–ethylene glycol solution containing Ce3+ and Zr4+ ions was polymerized at 80–110 °C to form a viscous transparent resin without any visible precipitation. After heat-treatment at relatively low temperature (ca 250 °C) on a hot plate...
