dc.description.abstractМетодом циклічної вольтамперометрії досліджено каталітичну активність нано- структурованих Pd-Au/GC електродів у реакціях електрохімічного окиснення СН3ОН у лужному середовищі. Встановлено, що під час електрохімічного окиснення метанолу на поверхні Pd-Au/GC проявляється послідовна каталітична дія компонентів Pd та Au. Збільшення вмісту паладію пришвидшує повне окиснення метанолу, сприяючи зменшенню вмісту проміжних сполук, що підтверджує високу ефективність наноструктурованих Pd-Au/GC електродів.
dc.description.abstractThe catalytic activity of nanostructured Pd-Au in electrochemical oxidation of СН3ОН in an alkaline environment was researched by the method of cyclic voltammetry. It was found, that during the in electrochemical oxidation of methanol on the surface of the Pd-Au/GC electrode is manifested sequential catalytic action of components Pd and Au. An increase in the content of palladium accelerates the complete oxidation of methane, contributing to a decrease in the content of intermediates, indicating the high efficiency of nanostructured Pd- Au/GC electrodes.
