Research Progress of MoS₂Composite rGO Material in Gas Sensor

Abstract

Since the successful preparation of single-layer graphene in 2004, two-dimensional materials have gradually become one of the research hotspots in the field of materials science. However, due to the inevitable defects of intrinsic two-dimensional materials, researchers began to explore how to obtain more excellent two-dimensional materials. In this paper, the basic properties, preparation methods and application in gas sensors of MoS2/rGO composites are reviewed. This paper has a certain reference value for the research of two-dimensional materials used in gas sensors.

Highly Efficient MoS2/CsxWO3 Nanocomposite Hydrogen Gas Sensors

“…Among the different types of gases, MoS 2 nanostructures are usually selective toward NH 3 gas at room temperature, which hinders their applicability as gas sensors. Although MoS 2 is a good sensing material, it has limitations, such as a low structural strength and conductivity (Huaning et al, 2021). However, few studies have shown that its selective behavior can change while forming hybrids with different materials; this can be ascribed to the charge-transferbased modulation of the channel conductivity of the gas sensor mechanism (Gottam et al, 2020).…”
