Abstract

Electrochemical deposition technique was utilized to fabricate nickel nanotubes with the assistance of AAO templates. The topography and element component of the nickel nanotubes were characterized by TEM and EDS. Furthermore, the nickel nanotube was made into microelectrode and its electrochemical hydrogen storage property was studied using cyclic voltammetry. The results showed that the diameter of nickel nanotubes fabricated was around 20–100 mm, and the length of the nanotube could reach micron grade. The nickel nanotubes had hydrogen storage property, and the hydrogen storage performance was higher than that of nickel powder.

Highlights

In recent years, great importance has been attached to onedimensional nanomaterials such as nanowire and nanotube by researchers increasingly due to the unique characteristics and the potential application prospects in the fields of microelectrode [1], single-electron devices [2], chemical sensors, catalysts, and so on [3]
The aluminum oxide template was put into the above-mentioned sensitization solution to soak for a few minutes to be sensitized, and it was washed by deionized water
The surfaces of the anodic aluminum oxide (AAO) template fabricated by phosphoric acid solution and sulfuric acid solution do not show obvious porous structure, which may be because the fact that the acidity of phosphoric acid and sulfuric acid is strong, and when the porous structure is formed, it is dissolved immediately

Summary

Introduction

Great importance has been attached to onedimensional nanomaterials such as nanowire and nanotube by researchers increasingly due to the unique characteristics and the potential application prospects in the fields of microelectrode [1], single-electron devices [2], chemical sensors, catalysts, and so on [3]. It has been one of the research hotspots to use chemical and physical methods to prepare highly ordered one-dimensional nanomaterials (nanowire and nanotube). Explore and study whether they had application value as nickel-metal hydride battery electrode materials
