A facile aqueous sol–gel method for high surface area nanocrystalline CeO2

Abstract

Thermally stable high surface area nanocrystalline CeO2 was synthesized via an aqueous sol–gel method using cerium hydroxide and urea as precursors. The CeO2 sol is yellow colored and absorbs light over the range 200–500 nm. Nanocrystalline CeO2 particles derived from the sol are spherical in shape and range from 9 to 13 nm in diameter. The CeO2 powder has a high surface area of up to 85 m2 g−1 and a band gap of 3.1 eV. The method of preparation is facile, utilises low cost reagents and can be performed on a large scale.
