Cu<sub>x</sub>O Nanostructure-Based Gas Sensors for H<sub>2</sub>S Detection: An Overview
H<sub>2</sub>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...

| description | H<sub>2</sub>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<sub>2</sub>S is Cu<sub>x</sub>O (x = 1, 2), which is converted to Cu<sub>x</sub>S upon exposure to H<sub>2</sub>S, leading to a remarkable modulation in the resistance and appearance of an electrical sensing signal. In this review, various morphologies of Cu<sub>x</sub>O in the pristine form, composites of Cu<sub>x</sub>O with other materials, and decoration/doping of noble metals on Cu<sub>x</sub>O nanostructures for the reliable detection of H<sub>2</sub>S gas are thoroughly discussed. With an emphasis to the detection mechanism of Cu<sub>x</sub>O-based gas sensors, this review presents findings that are of considerable value as a reference. |
