Disclosed herein are a method for forming a pattern of a one-dimensional nanostructure, and a pattern of a one-dimensional nanostructure formed by the method. The method comprises the steps of (i) coating a photocatalytic compound onto a substrate to form a photocatalytic film, and selectively exposing the photocatalytic film to light to form latent image centers for crystal growth, (ii) growing metal crystals by plating the latent pattern to form a metal pattern, and (iii) selectively growing a one-dimensional nanostructure on the metal pattern acting as a catalyst.
