Electrooxidation Of Methanol On Multilayer Films Of Polypyrrole-Platinum Electrode, Ling Zhang, Long-Zhen Zheng
Electrooxidation Of Methanol On Multilayer Films Of Polypyrrole-Platinum Electrode, Ling Zhang, Long-Zhen Zheng
Journal of Electrochemistry
Multilayer films of polypyrrole-platinum electrode were fabricated by cyclic voltammetric technique.Electro-oxidation of methanol on this electrode was investigated with the aid of cyclic voltammetry and chronoamperometry.Results demonstrated that the multilayer of polypyrrole-platinum electrode behaved better electrocatalytic performance for electro-oxidaton of methanol and better poison resistant.Furthermore,with the increase of deposited platinum loadings,the rate controlling step on electro-oxidation reaction of methanol was changed from CO oxidation to sorption-desorption of hydrogen.

Determinations In Reducing Degree Of Iron-Amine Complex By Cyclic Voltammetry, Yu-Kun Lai, Wei Wang
Journal of Electrochemistry
The veracity and influence factors in reducing degree on iron-amine complex were tested by cyclic voltammetry.The types of cathode electrolytes including ferric nitrate,triethanolamine,sodium hydroxide and calcium nitrate were optimized.Compared with dip-dyeing coloration method,the cyclic voltammetry method can be used to measure the reducing degree of iron-amine complex more accurately with better stability,easier and faster operation.Potential applications of cyclic voltammetric determination method can be found in the fields of electrochemical dye production and related quality control.
