Evidence of local pH changes during ethanol oxidation at Pt electrodes in alkaline media**
Local changes of the interfacial pH can significantly affect the rate and mechanism in the course of an electrodic reaction. For instance, different pH values will have significant effect on the equilibrium properties of both solution and surface species altering the reactions kinetics. Ethanol oxidation at platinum electrodes, in alkaline media involves a fast consumption of OH species that wi...
متن کاملEthanol Electrooxidation using Ti/(RuO2)(x) Pt(1-x) Electrodes Prepared by the Polymeric Precursor Method
Este trabalho descreve um estudo detalhado da oxidação eletroquímica de etanol sobre eletrodos de Ti/(RuO2)(x)Pt(1-x) com várias composições, preparados pelo método de precursores poliméricos. Os resultados obtidos usando voltametria cíclica e cronoamperometria mostraram que a melhor composição dos eletrodos de Ti/(RuO2)(x)Pt(1-x) para os processos de oxidação do CO e do etanol é Ti/(RuO2)(0.5)...
متن کاملElectrocatalytic Oxidation of Glucose at Gold Nanoparticle-modified PFC electrodes in an Alkaline Solution
The electrocatalytic oxidation of glucose at Au nanoparticle-modified PFC electrodes has been studied using voltammetry technique in a (5 mM glucose + 0.1 M NaOH) solution. The PFC electrode didn't show any activity in the potential of interest (i.e. −0.8 V to 0.8 V). However, a very interesting positive catalytic effect was observed upon modification of the electrode surface with gold nanopart...
متن کاملKinetic study of ethanol and methanol electro-oxidation on Pd-vulcan XC-72R/Cu electrocatalyst in alkaline media
Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...
