A Comprehensive Review of Gas Sensors Using Carbon Materials
Abstract:
In recent years, interest in carbon materials for use in gas sensors has increased. Carbon materials have unique electrical, optical and mechanical properties, making these materials very interesting. In this review, the properties of carbon materials are first introduced. Surface modification for carbon materials, fabrication for gas sensors, and the gas-sensing conditions and mechanisms according to the different types of carbon materials are chiefly described. In particular, this review focuses on the enhancement of the gas-sensing properties of carbon materials depending on the modification methods used and its mechanism.
