以多壁碳纳米管（MWCNT）为载体，以十六烷基三甲基溴化铵（CTAB）为添加剂，采用肼还原法制备了Ni/MWCNT催化剂。场发射扫描电子显微镜（FE-SEM）、X射线衍射（XRD）和高分辨透射电子显微镜（HR-TEM）分析表明，沉积在MWCNTs侧壁上的Ni纳米颗粒（NPs）为面心立方（fcc）晶体结构，分散均匀，粒径分布集中在20 nm左右。采用循环伏安法研究了乙醇在MWCNT/Ni催化剂上的电氧化反应。MWCNT/Ni催化剂对乙醇在碱性溶液中的氧化具有良好的电催化活性。
Multi-walled carbon nanotube (MWCNT) supported nickel (Ni) catalysts were chemically synthesized via a hydrazine reduction process with addition of cetyltrimethylammonium bromide (CTAB) as a special additive. As evidenced by field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and high-revolution transmission electron microscope (HR-TEM), the Ni nanoparticles (NPs) deposited on the sidewalls of MWCNTs were found to be face-centric cubic (fcc) crystal structure, and dispersed homogenously with a sharp particle size distribution centered at around 20nm of diameter. Electro-oxidation of ethanol on MWCNT/Ni catalysts was investigated by cyclic voltammetry (CV) measurement. The MWCNT/Ni catalysts showed excellent electro-catalytic activity for the oxidation of ethanol in alkaline solution.
