dc.description.abstractIn this work, synthesis of ultra-thin 2D CeO2nanoribbons is reported for the first time along with rod-shaped nanostructures via a surfactant free aqueous method. CeO2nanoribbons of length >100 nm have been synthesised through a mild reaction route involving ammonia precipitation and subsequent heating and ageing at 0 8C. 2D nanostructures are proposed to be formed as a result of self-assembly of CeO2 molecules. The ribbons exhibited amorphous X-ray diffraction pattern and TEM showed a ribbon like morphology with crystal facets of 0.33 nm spacing corresponding to (1 1 1) plane of CeO2. HR-TEM confirmed that the nanorods are enclosed by {1 1 1} planes and have preferentially grown in {1 1 0} direction. The surface area of the powder containing majority nanorods is 82 m 2 /g and their average pore size is 3 nm. The nanostructures exhibited optical band gaps dominated by the regular quantum confinement effect as well as presence of defects. # 2011 Elsevier Ltd and Techna Group S.r.l. All rights reserveden_US
