置换或金属沉积反应是用电动序较高的金属从溶液中沉淀电动序较低的金属的电化学过程。置换反应可表示为 :m Nn++ n M n Mm++ m N式中 ,N代表贵金属 ,M为还原剂金属。铝置换铜的总反应式为 :Cu2 ++ 2 /3Al Cu+ 2 /3Al3+旋转圆盘电极装置已广泛用于各种置换反应的动力学研究 ,发
Displacement or metal deposition reactions are electrochemically processes that deposit electrically less-ordered metals from solution using higher electromotive force metals. The displacement reaction can be expressed as: m Nn ++ n M n Mm ++ m N wherein N represents a noble metal and M a reducing metal. The total reaction of aluminum displacement copper is: Cu2 + +2 / 3Al Cu +2 / 3Al3 + rotating disk electrode device has been widely used in a variety of displacement reaction kinetics, hair
