CuO/G yapılarının analitik karakterizasyonu için XRD ve EDS teknikleri kullanılmıştır. Morfolojik karakterizasyonu ise SEM kullanılarak yapılmıştır. CuO/G kompozitlerinin etanol elektro-oksidasyon reaksiyonunda elektrokatalizör olarak kullanımı incelenmiş ve dönüşümlü voltametri tekniği kullanılarak katalitik özellikleri araştırılmıştır. Etanol oksidasyonu için en yüksek akım yoğunluğu CuO/G kompozitinde elde edilmiştir. Sentezlenen nanokompozit filmin yakıt hücrelerinde elektrot malzemesi olarak kullanılabileceği belirlenmiştir.

Electro-oxidation of Ethanol on CuO-graphene Nanocomposites

Abstract

In this study, electrochemical deposition of CuO-graphene (CuO/G) nanocomposites on Au electrode was performed via one-pot electrochemical deposition technique. XRD and EDS techniques were used to for analytical characterization of CuO/G films. Then, morphological characterization of composite was carried out by SEM. The Au-CuO/G electrode was examined as an electrocatalyst for ethanol electro-oxidation reaction and properties of electrocatalyst was investigated by using cyclic voltammetry. The highest current density for ethanol electro-oxidation was determined at CuO/G modified electrode. Also, as-prepared CuO/G nanocomposites can be used to as electrode in fuel cell applications.
