通过调节水热工艺制备了两种纳米 TiO2和Mn O 2氧化物,采用涂覆法得到了3种修饰活性炭纤维(ACF)电极,并借助透射电镜(TEM)和循环伏安法(CV)等手段对 TiO2和 MnO2的形貌与尺寸,修饰ACF电极的电化学性能等进行了表征。结果表明, TiO2和 MnO2均为一维纳米结构,其中 TiO2为棒状,MnO2属管态;在电极体系中,由 TiO2和 MnO2修饰的二元ACF电极凸显了较高的导电性,其电流密度的顺序依次是 ACF
In this paper,two nano-TiO2 and MnO2 oxides were synthesized by hydrothermal method,and three kinds of modified activated carbon fiber (ACF)electrodes were fabricated by dip coating process using both ox-ides.The morphology and dimension of the oxides were characterized by TEM and the electrochemical property of modified ACF electrodes was evaluated with cyclic voltammetry (CV).The results showed that two oxides are one-dimensional nano-sized materials,that was,TiO2 rodand MnO2 tube.Besides,an enhanced electrical conductivity of the modified ACF electrode was observed after coating with both TiO2 and MnO2 .And the elec-tronic density of modified ACF electrodes lied in the sequence of ACF
