Abstract

A novel and facile method is applied to successfully synthesize the 20 mol% neodymium-doped ceria (CNO) nanomaterials, including nanowires and nanoparticles, at 240 °C in ambient air. These special nanostructures are easily densified at 1300 °C and provide a three-dimensional (3D), continuous and fast ionic conduction pathway. Surprisingly, the CNO nanomaterials endow the homogeneous and compact ceramics with a competitive ionic conductivity of ∼1.5 S m−1 at 600 °C, down to a pO2 value of about 10−4 atm, and act as a potential electrolyte or composite anode for intermediate-temperature solid oxide fuel cells.
