ABSTRACT

By controlling the composition of the metal-oxide nanosheet having a two-dimensional layered crystal structure,material properties and application can be extended. In this study, the composition of the nanosheet could be expanded from pure composition to doping composition by successfully synthesizing the TiO2 nanosheet doped with Nb. Specifically, thedoping composition was designed when synthesizing the layered metal oxide as a starting material (K0.8Ti1.73-xNbxLi0.27O4,x = 0, 0.03, 0.07) and chemical exfoliation was performed. By doing this, it was possible to obtain the Nb-doped TiOy ultrathin nanosheet. The size of the nano sheet was 2 μm or less based on the long length in the x-y direction, and the thickness was about 1 nm. Nb-doping was confirmed by XRD and SEM-EDS analysis.
