Fabrication of Hollow Tetrapod‐Like TiN Nanostructures and Its Electrochemical Property
The facile synthesis of tetrapod‐like TiN nanocrystals with a hollow and porous structure is described. The nanocrystals were prepared by nitridation of a ZnO/TiO2
core/shell structure consisting of a thin shell of tiny TiO2 nanoparticles deposited onto a tetrapod‐like ZnO core by a vapor‐hydrolysis process. The ZnO
core was then removed by vaporization during the nitridation step. The resulting hollow and porous TiN particles were with a crystallite size of 24 nm, and the shape of the tetrapod‐like ZnO template
preserved. The combination of the hollow and porous structure and novel morphology enhanced the electrochemical activity.
