Hydrothermal Synthesis of Single-Crystal Ni(OH)2 Nanorods in a Carbon-Coated Anodic Alumina Film

The formation of Ni(OH)2 nanorods within an anodic oxide template via hydrothermal synthesis, followed by their subsequent liberation to form discrete NiO nanorods, is presented. The carbon can effectively be removed to form this uniform rod-like product. The Figure shows a schematic illustration of the synthesis.
