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.
关键词 Pd - Ag 合金 H 传感器 电化学
ABSTRACT In this article ,the elect rochemical performance of Pd - Ag alloy elect rode in KOH alka2 line solution was studied. The reaction mechanism of Pd( Pd - Ag) - H2 system was discussed and the quantitative relationship between sensor response and hydrogen content was acquired. Pd - Ag alloy elect rode is suitable for using as selective catalytic anode of hydrogen sensor. The elect rochemical hy2 drogen sensor based on Pd - Ag alloy anode exhibit s high sensitivity and good repetition.
