本文采用TEM、循环伏安、阻抗-电位等方法,研究比较了碳纳米管/纳米TiO2复合膜(CNT/nano—TiO2)修饰电极与纯纳米TiO2(nano—TiO2)膜电极电化学性能的差异。大量细小的碳纳米管的存在,可起到阻碍TiO2纳米粒子的团聚作用,从而提高了CNT/nano-TiO2修饰电极的电化学性能。
In terms of TEM,Cyclic Voltammetrv and Impedance-potential spectra, the paper researches and compares the electrochemical characteristic difference between complex C-nanotube/nano-TiO2(CNT/nano-TiO2) modified electrode and nano-TiO2 electrode, a great deal of carbon nanotubes are in existence, which can block aggregation of nano-TiO2 particle.It proves electrochemical functions of CNT/nano-TiO2 modified electrode.
