İletken poli(tiyonin) filminin Pt partikülleri için destek malzemesi olarak kullanılması: Metanol yükseltgenmesine karşı elektrokatalitik aktivite

Bu çalışmada kalem grafit elektrot üzerinde Pt@PTH katalizör sisteminin sentezi ve metanolün elektroyükseltgenmesi için kullanımı anlatılmaktadır. Deneysel koşulların katalizör sisteminin performansı üzerine olan etkisi, destek elektrolit olarak H2SO4 içeren metanol çözeltisinin dönüşümlü voltamogramları kaydedilerek saptanmıştır. Optimum koşullarda hazırlanan katalizörün fiziksel karakterizasyonu Taramalı Elektron Mikroskobu, Enerji Dağılımlı X-Işınları Spektroskopisi ve Elementel Haritalama ile gerçekleştirilmiştir. Elektrokimyasal karakterizasyon için ise H2SO4 çözeltisinde dönüşümlü voltametri yöntemi kullanılmıştır.

Conducting poly(thionine) film as a support material for Pt particles: Electrocatalytic activity towards methanol oxidation

Facile synthesis of Pt@PTH catalyst on pencil graphite electrode for electrooxidation of methanol was described. Influence of experimental conditions on the performance of the catalyst system was studied by recording cyclic voltammograms of methanol solution containing H2SO4 as the supporting electrolyte. The catalyst prepared under optimum conditions was physically characterized using Scanning Electron Microscopy, Energy Dispersive X-Ray Dispersion and Elemental Mapping methods. Electrochemical characterization was performed by cyclic voltammetry in H2SO4 solution.
