Resumo
The exceptional properties arising from versatility in composition, morphology,
and structure, two-dimensional (2D) layered nanomaterials have attracted huge
interest in the last decade. Such materials, consisting in stacked charged
nanosheets intercalated with opposite charged exchangeable anions, are of great
potential for the design and fabrication of nanostructures in many applications.
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.
