Alkali concentration-dependent tailoring of highly controllable titanate nanostructures: From yolk-shell, hollow 3D nanospheres to 1D nanowires

Highly controllable titanate nanostructures assembled from anisotropic building blocks, such as yolk-shelled nanospheres, hollow hierarchical titanate 3D nanospheres and 1D nanowires were successfully fabricated through a facile alkali concentration-dependent approach. All products with unique morphologies exhibit catalytic performance up to 86.9% towards the oxidation reaction of styrene.
