Abstract

The sensitivity of gas sensors made of doped SnO₂:Co metal oxide for the detection of hydrogen peroxide vapors in the environment was studied using current-voltage, frequency-capacitance, and transient characteristics. Their measurements were carried out at room temperature under the influence of ultraviolet light and without it. It is shown that the influence of ultraviolet rays on the active surface of the sensor increases the gas sensitivity of the sensor. Studies of transient characteristics have also shown that the resistance of the sensor when it is exposed to ultraviolet rays, already at room temperature, after the feeding-off of hydrogen peroxide vapors is almost completely restored.

紫外线照射下过氧化氢蒸气检测传感器的研究

摘要

利用电流-电压，频率电容和瞬态特性研究了由掺杂SnO ₂：Co金属氧化物制成的气体传感器对环境中过氧化氢蒸气的检测灵敏度。他们的测量是在室温下在紫外线的影响下进行的，没有紫外线。示出了紫外线对传感器的有源表面的影响增加了传感器的气体灵敏度。对瞬态特性的研究还表明，传感器的电阻在已经过室温的过氧化氢蒸汽排出后几乎已经恢复到室温时暴露于紫外线下。
