| Description | $H_{2}$S gas is a toxic and hazardous byproduct of the oil and gas industries. It paralyzes the olfactory nerves, with concentrations above 100 ppm, resulting in loss of smell; prolonged inhalation may even cause death. One of the most important semiconducting metal oxides for the detection of $H_{2}$S is $Cu_{x}$O (x = 1, 2), which is converted to $Cu_{x}$S upon exposure to $H_{2}$S, leading to a remarkable modulation in the resistance and appearance of an electrical sensing signal. In this review, various morphologies of $Cu_{x}$O in the pristine form, composites of $Cu_{x}$O with other materials, and decoration/doping of noble metals on $Cu_{x}$O nanostructures for the reliable detection of $H_{2}$S gas are thoroughly discussed. With an emphasis to the detection mechanism of $Cu_{x}$O-based gas sensors, this review presents findings that are of considerable value as a reference. |
