Abstract
The presence of hydrogen sulfide (H2S) determines the air quality of both indoor and outdoor environments. To measure H2S concentration levels in the environment, a variety of sensors have been developed. metal oxide (MO
x
) based gas sensors are among the most interesting class of MEMS sensors, capable of producing highly sensitive, selective, and specific signals in a plethora of chemical and physical signals. Nonetheless, in the presence of moisture, they have poor selectivity and response. However, the sensing performance of MO
x
towards H2S gas is previously reported in a number of studies. Nanotechnology advancements are expected to lead to the progress of highly sensitive, stable, and selective MO
x
-based H2S gas sensors in the future. This review article aims at enlightening the various aspects of H2S gas sensing technology in an unpretentious yet comprehensive manner.
