Carbon monoxide is one of the most important reducing gases to be
detected in combustion of hydrocarbon fuels, petroleum and
automobile industries, heat-treating furnaces and, also in the first
stages of fire. During the past four decades, gas sensors based either
on the surface characteristics or the bulk properties of ceramics have
been the subject of extensive research and development. New
materials research endeavors are leading to the development of new
solid-state devices for CO detection and metering. Nevertheless, even
the most recent development in this area falls short of what is desired
and required in real-life, e.g., selectivity, sensitivity, response-time
and reversibility. This review attempts to take stock of the present day
scenario of the advances made towards the development and
performance of solid-state chemical sensors for carbon monoxide. In
addition, some recent results on the development of CO sensors for
NASA's proposed Manned Mars Mission are also presented.
