POROUS NANO STRUCTURE AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A porous nanostructure and a producing method thereof are provided to remarkably increase the surface area of the nanostructure by producing pores on the surface and the inside of the nanostructure. CONSTITUTION: A porous nanostructure includes pores(12) formed on the surface and the inside of the nanostructure(10). The pores are through-holes. The nanostructure is either a nanotube or a nanowire. The nanostructure contains a p-type or an n-type dopant. A producing method of the nanostructure comprises the following steps: attaching nanoparticles on the surface of the nanostructure; oxidizing the nanostructure for forming oxides on the surface of the nanostructure; and removing the oxides and the nanoparticles from the nanostructure.
