镍 (Ni) 总是通过直接电沉积的方式积聚在多壁碳纳米管 (MWCNT) 上。本文通过分子水平设计，将镍纳米粒子电结晶在多壁碳纳米管上接枝的4-硝基苯胺（NA）自由基单层上。通过场发射扫描电子显微镜（FE-SEM）、X射线衍射（XRD）和X射线光电子能谱（XPS）对Ni/NA/MWCNT的结构和性质进行了表征，结果表明Ni纳米颗粒均匀电沉积在MWCNT表面。该复合催化剂对碱性溶液中乙醇的氧化表现出优异的电催化活性。
Nickel (Ni) always accumulates on multi-walled carbon nanotubes (MWCNT) by direct electrodeposition. In this paper, nickel nanoparticles were electro crystallized on 4-nitroaniline (NA) radical monolayer-grafted on MWCNT through molecular level design. The structure and nature of the Ni/NA/MWCNT were characterized by field emission scanning electron microscope (FE-SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), the results show that Ni nanoparticles were homogeneously electrodeposited on the surfaces of MWCNT. This complex catalyst showed excellent electro-catalytic activity for oxidation of ethanol in alkaline solution.
