Özet

In this study, high efficiency of a ternary electrocatalyst NiFeMo electrodeposited on a nickel coated nickel foam was researched to be used as cathode material in AEM alkaline water electrolyser. The electrocatalytic activity was studied with electrochemical techniques such as linear sweep voltammetry (LSV), Electrochemical Impedance Spectroscopy (EIS), Cyclic Voltammetry and Chronopotentiometry. Also, Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) analysis were used to characterize the surface morphology which showed successful deposition of the catalysts. Tafel slopes were obtained as 212 mV dec−1, 216 mV dec−1 and 185 mV dec−1 for foam, #Ni and NiFeMo#Ni respectively. In addition, the catalyst was tested in a glass cell with a Fumasep membrane and the volume of hydrogen gas obtained was the highest compared to the foam and Ni.
