| 中文摘要 | 本研究主要以微陽極導引製程(Micro-anode guided electroplating, MAGE),藉由控制鎳鈷合金鍍浴中 硫酸鈷濃度於 0 M ~ 0.1 M 範圍中來製備不同鈷含量的鎳鈷合金微柱。並藉助 Scanning Electron Microscope (SEM)觀察微柱之表面形貌、Energy-dispersive X-ray spectroscopy (EDS)分析化學組成及 X- ray diffractometer (XRD)分析晶體結構。隨後,將這些不同組成之鎳鈷合金微柱浸泡至 1 M KOH 溶液 中,以探討其產氫性能之差異。實驗結果顯示鍍浴中含 0.08 M [Co2+]時所製得之微柱 Ni55Co45 擁有最低 的 Tafel 斜率(110 mV/dec)和最小的 η10 (159 mV)過電位,最具潛力來作為鹼性水電解產氫的陰極材料。 |
| 英文摘要 | This study utilizes the micro-anode guided electroplating (MAGE) process to create nickel-cobalt alloy micropillars with varying cobalt concentrations. This was done by adjusting the cobalt sulfate concentration in the nickel-cobalt alloy plating bath within the range of 0 M to 0.1 M. The surface morphology of the micropillars was observed using Scanning Electron Microscope (SEM), while the chemical composition was analyzed using Energy-dispersive X-ray spectroscopy (EDS), and the crystal structure was analyzed using X-ray diffractometer (XRD). Following this, the nickel-cobalt alloy micropillars with different compositions were tested in 1 M KOH solution to investigate their hydrogen production properties. The experimental results indicate that the micropillar Ni55Co45, which was prepared when the plating bath contained 0.08 M [Co2+], exhibited the most minimal tafel slope (110 mV/dec) and the smallest overpotential η10 (159 mV). It also showed the highest potential as a cathode material for hydrogen production through alkaline water electrolysis. |
