在5mmol/L H2PtCl6的稀硫酸溶液中,采用循环伏安法(CV),扫描电位为-0.2～0.6V和0.0～0.6V,分别扫描30和15循环,在碳纳米管/纳米TiO2-聚苯胺复合膜上实现了Pt纳米粒子的高度有效分散,得到多壁碳纳米管/纳米TiO2-聚苯胺载铂四组分纳米结构复合电极,通过CV法和计时电位法并结合扫描电镜对复合电极的电化学性质和结构进行表征,研究了复合电极对葡萄糖的电催化氧化性能。结果表明,该复合电极对葡萄糖的电氧化有高催化活性,具有性能稳定、重现性好、抗毒化作用强、能耐高温、易保存且使用寿命较长的优点。
Cyclic voltammetry (CV) was used in the dilute sulfuric acid solution of 5 mmol / L H2PtCl6. The scanning potentials were -0.2 ~ 0.6V and 0.0 ~ 0.6V. After scanning for 30 and 15 cycles respectively, Aniline composite membrane to achieve a highly efficient dispersion of Pt nanoparticles to obtain multi-walled carbon nanotube / nano-TiO2-polyaniline platinum composite four-component nanostructured composite electrode by CV method and combined with scanning electron microscopy composite electrode The electrochemical properties and structure of the composite electrode were studied. The electrocatalytic oxidation of glucose by the composite electrode was studied. The results show that the composite electrode has high catalytic activity for the electrooxidation of glucose, has the advantages of stable performance, good reproducibility, strong anti-poison effect, high temperature resistance, easy storage and long service life.
