Abstract

Undoped and doped ceria were synthesized by a solid state reaction and a polymerized—complex method. Microstructural and phase development of M_xCe_1-xO_2-δ (M = Zr, Hf; 0 ≤ x ≤ 0.2) were examined using X-ray diffraction and scanning electron microscopy. Redox properties were investigated by thermogravimetric analysis and a remarkable increase of the oxygen storage capacity of ceria with increasing dopant concentration was demonstrated. Zr_xCe_1-xO₂ and Hf_xCe_1-xO₂ solid solutions at x = 0.2 were shown to release double the amount of oxygen during reduction compared to undoped ceria. The solid state reaction synthesis produces materials with excellent redox performance up to 15 mol% dopant concentration and is otherwise equivalent with materials produced by Pechini synthesis.
