摘要
研究了Pd -Ag合金电极在KOH溶液中的电化学行为 ,讨论了H在Pd -Ag合金上的作用原理并推导出传感器响应信号和氢气量的定量关系 ,指出Pd -Ag合金适合于作为氢传感器的选择性催化阳极并研究了以Pd -Ag合金为阳极的电化学氢传感器的性能特点 .
In this article,the electrochemical performance of Pd-Ag alloy electrode in KOH alkaline solution was studied.The reaction mechanism of Pd(Pd-Ag)-H 2 system was discussed and the quantitative relationship between sensor response and hydrogen content was acquired.Pd-Ag alloy electrode is suitable for using as selective catalytic anode of hydrogen sensor.The electrochemical hydrogen sensor based on Pd-Ag alloy anode exhibits high sensitivity and good repetition.
