• 中文摘要： 本研究應用實驗計畫法探究鎳-二硫化鉬複合電鍍的程序特性。就所選定的五項因子言,實驗數據經統計分析顯示鍍液溫度及pH為具顯著性的因子,而電極轉速則為次要因子。實驗結果示明鍍層中二硫化鉬含量隨pH上升而增大,但隨鍍液溫度上升而下降。本研究所製得的複合鍍層經在鹼性溶液中測試,證明其析氫催化能力優於純銅及純鎳鍍層,且當複合鍍層中二硫化鉬重量含量約34%時,催化活性最優
• 英文摘要： Composites containing molybdenum disulfide of various contents in a nickel matrix were prepared using composite electrodeposition technique in this study. The nickel- molybdenum disulfide system, as a hydrogen electrode in alkaline solutions, exhibited a more significant increase in electrocatalytic property than pure copper and electrodeposited nickel. Moreover, the electrocatalytic performance displayed an optimum efficiency at 34% by weight of the MoS/sub 2/ in deposit. We also examined the process characteristics of codepositing MoS/sub 2/ particles with nickel using statistical experimental design in order to obtain a better understanding of the process. The critical factors in codepositing nickel and molybdenum disulfide particles were investigated. According to those results, the pH value and bath temperature are of primary importance. Rotation rate of electrode is a secondary significant factor. The extent of code-position increases with the pH value of the bath. The extent of incorporating the MoS/sub 2/ phase, however, decreases with the solution's temperature.
