Unidirectionally Aligned Copper Hydroxide Crystalline Nanorods from Two-Dimensional Copper Hydroxy Nitrate

Abstract

We were able to synthesize unidirectionally aligned copper hydroxide nanorods from two-dimensional copper hydroxide nitrate by anion exchange reaction using NaOH without any membrane or template. The structural conversion from Cu2(OH)3NO3 to Cu(OH)2 was confirmed by XRD and FT-IR data. The synthesized copper hydroxide nanorods showed unidirectionally aligned and tightly bound arrays on a hexagonal plate, leading to giant nanorod bundles.
