Preparation of TiO2, CeO2, and ZrO2 hierarchical structures in “one-pot” reactions

Construction of TiO2 Hierarchical Nanostructures from Nanocrystals and Their Photocatalytic Properties

“…On the one hand, they own the advantages of enhanced light absorption, as a result of multireflection within the numerous voids of the materials, thus usually exhibiting higher photo efficiency. − On the other hand, the assembled nanostructures provide much more exposed surface region, well facilitating the adsorption and photoreaction of reactants. Till now, many inorganic photocatalytic materials are able to be prepared in flower like hierarchical structures, such as Bi 2 WO 6 , Bi 2 MoO 6 , ZnO, ,, CeO 2 , and BiOX (X = Cl, Br, I). , …”

Controlled synthesis of hierarchical flower-like Sb 2 WO 6 microspheres: Photocatalytic and superhydrophobic property

“…The three-dimensional (3D) nano composites are widely applied in chemical separations [14], heterogeneous catalysis [15], biosensors [16] and electrochemical [17], due to its large surface area and unique crystal structures. Up to now, various 3D hierarchical spheres, including ZnO [18], BiOI [19], CeO 2 [20], Bi 2 WO 6 [21] have been successfully fabricated with assistances of surfactants. However, these self-assembly structures were easily collapsed after removing surfactants from the solvents.…”
