Abstract

A solid-state amperometric sensor for NO₂ was designed by attaching a Na⁺ conductor (NASICON) based device with an NaNO₂ layer deposited on the counter electrode. With the sensing electrode being polarized at a constant potential relative to the reference Au electrode, electric current flowing through the device under exposure to NO₂ was measured as the sensing signal. The current response was almost linear to the NO₂ concentration in the range from 10 ppb to 1 ppm at 150°C. The 90% response time to even 20 ppb NO₂ was ca. 60 s. The NO₂ sensitivity was hardly affected by the coexistence of CO₂, H₂O and O₂. A sensing mechanism is proposed from the sensing characteristics obtained.
