Resumo
By the virtue of versatility in composition, morphology, and structure, two-dimensional (2D) layered
nanomaterials have attracted in the last decade huge interest. Such materials, consisting in stacked charged
nanosheets intercalated with opposite charged exchangeable anions, are of great potential for the design and
fabrication of nanomaterials in many applications. Indeed, the interlayer gallery provides a flexible space to
accommodate various sized molecules (e.g. pollutants) and tune specific active sites at the atomic space (e.g.
catalyst materials). The interest for 2D layered nanomaterials is also associated with the possibility of
obtaining via exfoliation ultra-thin nanosheets with lateral dimensions of hundreds of nanometres and
thickness of few nanometres. This unique class of nanomaterials has shown many unprecedented properties
mainly originating from the dimensional anisotropy and nano-confinement effects.
Herein we propose novel 2D layered ceria based oxides (e.g. CGO) synthesized via the heterogeneous
precipitation. CGO materials were selected because of their strategic relevance in many technological
applications (e. g. catalysis and electrochemical devices). The synthesized CGO layered materials were
characterized for their composition, morphology and crystallographic features. The combined experimental
results indicated that the layered CGO, with tunable dopant concentration, can be obtained in different
morphologies by controlling the synthesis parameters.
