甲烷体积分数电化学传感器稳定性分析

直接的甲烷电化学检测是通过在电极表面直接氧化甲烷或吸附甲烷导致电流或者电压发生变化来检测。首先采用循环伏安法在镍电极表面修饰了氢氧化镍,制备出氢氧化镍修饰镍电极,然后通过甲烷的氢氧化镍电化学实验,分析甲烷在镍电极上的电化学行为,得到甲烷的电催化活性和电化学传感器的稳定性。从而证明此类电化学传感器在甲烷体积分数检测上的可应用性。

Stability Analysis of Methane Volume Fraction Electrochemical Sensors

Direct electric chemical methane detection is detected by the change of voltage or current leaded by the methane oxidation or adsorption methane in the electrode surface.First,cyclic voltammetry was employed to modify nickel-hydrogen on the surface of the nickel electrode,and to prepare modified nickel-hydrogen nickel electrode,then the electricity catalytic activity and electrochemical sensor stability of the methane is shown up through analysising the electrochemical behavior of the methane on the nickel electrode,on the basis of the nickel hydroxide electrochemical experiment of the methane.So the applicability of the electrochemical sensor in methane volume fraction measurement can be proved.
