用电化学方法制备了Ni、In电极和A、B两种不同类型Ni_In合金电极，考察了这些电极在0．2 mol／L NaOH溶液中的伏安行为；同时讨论了葡萄糖在所制电极表面的催化氧化行为．结果表明：在碱性介质中Ni电极和Ni_In合金电极对葡萄糖的氧化都有一定的催化作用，其中A型 Ni_In合金电极的催化作用最强；在镀液中Ni~(2+)、In~(3+)抖摩尔比为5：1时得到的A型Ni-In合金电极对葡萄糖催化效率最高，同时葡萄糖浓度在1～10 mmol／L之间与其氧化峰电流成线性关系．A型Ni．In合金电极性能稳定，抗中毒能力强，可以作为葡萄糖燃料电池的高催化活性电极．

The Ni,In electrodes and two kinds of Ni-In electrodes were prepared by electrochemical methods and their vohammetric behaviors were investigated in 0.2 mol/L NaOH solution. The electrocatalytic activities of glucose on electrode surface were also discussed. The results indicated that Ni and Ni-In electrodes showed catalysis effect on glucose oxidation in alkaline solution and the catalytic action of the A-type Ni-In alloy electrode was best. The A-type Ni-In alloy electrode, which prepared at condition of Ni^2＋ ,In^3＋ mole ratio 5 ： 1,had b...
