Abstract

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.

NiFeMo泡沫镍作为碱性水电解槽正极材料的研究

在本研究中，研究了在包镍泡沫镍上电沉积的高效三元电催化剂NiFeMo作为AEM碱性水电解槽正极材料。采用线性扫描伏安法（LSV）、电化学阻抗谱（EIS）、循环伏安法和时间电位法等电化学技术研究了其电催化活性。利用扫描电镜（SEM）和x射线衍射（XRD）对催化剂表面形貌进行了表征，表明催化剂沉积成功。泡沫、#Ni和NiFeMo#Ni的Tafel斜率分别为212 mV dec−1、216 mV dec−1和185 mV dec−1。此外，在带有Fumasep膜的玻璃电池中对催化剂进行了测试，与泡沫和Ni相比，获得的氢气体积最高。

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
