Redox and Oxygen Evolution Electrocatalytic Properties of Nafion and Single-Walled Carbon Nanotube/Hydrous Iron Oxide Composite Films

摘要: Novel Nafion and single-walled carbon nanotube composite hydrous iron oxide electrodes have been fabricated using a simple potential cycling methodology are examined as oxygen evolution electrocatalyst films. Hydrous materials prepared in this manner typically quite amorphous nature. Here, we show, scanning electron microscopy cyclic voltammetry, that more uniform growth can be achieved or matrix template. This templated produces films with unique surface morphologies electrical properties. In particular, the exhibit superior conductivity, shown by electrochemical impedance spectroscopy, up to eightfold decrease charge transfer resistance. The ultimate result is an enhancement electrocatalytic performance of Fe film. Steady-state polarisation studies on reaction show reduction overpotential 50 mV for threefold increase turnover frequency.
