Effects of Additives on Gas Sensing Properties of In₂O₃Ethanol Gas Sensor

Abstract

The effects of additives on gas sensing properties of In 2 O 3 ethanol gas sensor were investigated. Gas sensors were fabricated by the painting method. The In 2 O 3 -La 2 O 3 -Pt sensor heat treated 400 o C displayed fast response and recovery behavior with a maximum sensitivity to ethanol gas in air at an operating temperature of 300 Received : May. 26, 2014, Revised : May. 27, 2014, Accepted : May. 28, 2014 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/ licenses/bync/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
