Electro Polymerization of o-Phenylenediamine Using Palladium Nanoparticles Coated Fabricated TiO2 Nanotubes Modified Glassy Carbon Electrode

摘要

Fabricated titanate nanotubes (f-TNT) are prepared by chemical deposition method using linen fiber. The f-TNTs is fabricated by TiO2 nanoparticles, the each TiO2 nanoparticles diameter has 80-100 nm in range. The Pd°nanoparticle was coated on the surface of thef-TNT by chemical reduction method, using NaBH4 as reducing agent. The prepared Pd7 f-TNTs characterized by FT-IR, FE-SEM and HRTEM, the result shows that the f-TNT diameter is 1500 nm and Pd nanoparticles range in 20-50 nm. The Pd/fTNT nanocomposite modified glassy carbon (GC) electrode shows quasi irreversible redox behaviours in cyclic voltammeter. Those Pd/f-TNTs modified electrode is utilized for electrochemical polymerization of o-phenylenediamine in acid medium.
