CNT Destekli Pd, Sn, Ir Tekmetalli Katalizörlerinin Metanol, Etanol, Etilen Glikol Elektrooksitlenme Aktivitesinin Araştırılması

Son zamanlarda nüfusun artması ve beraberinde sanayinin gelişmesinden dolayı enerji kaynaklarında hızlı bir şekilde azalma baş göstermiştir. Enerji kaynaklarının azalması bilim insanlarını yeni enerji kaynakları arayışı içine yönlendirmiştir. Yakıt pilleri yaygın bir şekilde enerji teknolojileri ile karşılaştırıldığında birçok avantaja sahiptir. Yakıt pillerinin verimi diğer konvansiyonel enerji sistemlerinden yüksektir. Yapılan bu çalışmada CNT destekli saf Pd, Sn ve Ir katalizörleri NaBH4 indirgeme yöntemi ile hazırlanmıştır. Bu katalizörlerin ICP-MS yöntemi ile karakterizasyonu yapılmıştır. Pd, Sn, Ir katalizörlerinin etanol, metanol, etilen glikol elektrooksitlenmesi döngüsel voltametre (CV), kronoamperometre (CA), elektrokimyasal empedans spektrokopisi (EIS) ölçümleri yapılmıştır.

Investigation of Methanol, Ethanol, Ethylene Glycol Electrooxidation Activity of CNT Supported Pd, Sn, Ir Catalysts

Recently, the energy need has been increased due to the increase in population and the development of industry. In order to meet the energy needs of the world, scientists have led the search for new sources of energy. Fuel cells are clean, efficient and promising sources of energy for the future. The efficiency of fuel cells is higher compared to other conventional energy systems. In this study, multi-walled carbon nanotube (CNT) supported Pd, Sn, and Ir catalysts were prepared by NaBH4 reduction method. These catalysts were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) method. Pd/CNT, Sn/CNT, and Ir/CNT catalysts were measured via cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) for ethanol (C2H5OH), methanol (CH3OH), and ethylene glycol (C2H6O2) electrooxidation.
