Electrode materials are an important component for the performance and life of electrochemical devices. Various metal and metal oxide materials are used as electrode materials for electrochemical devices. In this context, various studies are being carried out to improve the electrochemical properties of these materials. In this study, Ru/MgO metal/metal oxide nanomaterial was synthesized and its electrochemical properties were examined by cyclic voltammetry (CV) and galvanostatic charge and discharge (GCD) methods. Homogeneous Ru nanoparticles were obtained on MgO. According to the calculation made using the XRD pattern, the crystal size of Ru nanoparticles was approximately 4.2 nm. According to GCD measurements taken at different current densities, the highest specific capacitance was obtained with 239.0 F/g at 0.5 A/g.

Elektrot malzemeleri, elektrokimyasal cihazların performansı ve ömrü açısından önemli bir bileşendir. Elektrokimyasal cihazlarda elektrot malzemesi olarak çeşitli metal ve metal oksit malzemeler kullanılmaktadır. Bu bağlamda bu malzemelerin elektrokimyasal özelliklerinin iyileştirilmesine yönelik çeşitli çalışmalar yapılmaktadır. Bu çalışmada Ru/MgO metal/metal oksit nanomalzemesi sentezlenmiş ve elektrokimyasal özellikleri döngüsel voltametri (CV) ve galvanostatik şarj ve deşarj (GCD) yöntemleriyle incelenmiştir. MgO üzerinde homojen Ru nanopartikülleri elde edildi. XRD modeli kullanılarak yapılan hesaplamaya göre Ru nanopartiküllerinin kristal boyutu yaklaşık 4,2 nm idi. Farklı akım yoğunluklarında alınan GCD ölçümlerine göre en yüksek özgül kapasitans 0,5 A/g'de 239,0 F/g ile elde edilmiştir.
