摘要
本文以多孔氧化铝(AAO)为模板,采用电化学沉积法制备了镍纳米管,通过透射电镜(TEM),能谱仪(EDX),选区电子衍射图(SAED)对镍纳米管的形貌、微观结构及组成进行了表征。并将所制备的镍纳米管制成微电极,用循环伏安法测试了其电化学储氢性能。结果表明,所制备的镍纳米管管径约20nm,管长可达微米级,且相比于镍粉,镍纳米管的电化学储氢性能更好。
In this paper, electrochemical deposition technique was utilized to fabricate nickel nanotubes with the assistance of AAO templates. The topography, element component of the nickel nanotubes were characterized by TEM, EDX and SAED. Furthermore, the nickel nanotubes were made into mieroelectrode and its electrochemical hydrogen storage properties was studied using eyelie voltammetry. The results showed that the fabricated nickel nanotubes had a diameter of about 20nm and the length could reach micron level. Cyclic voltammetry tests showed that, the nickel nanotubes had certain hydrogen storage properties , and the hydrogen storage performance was signifieandy higher than that of nickel powder.
