Abstract

This research presents a resistive-type hydrogen (H₂) gas sensor based on a composite of palladium nanoparticles (Pd-NP) decorated on 2D-molybdenum disulfide (MoS₂) layer. The sensor fabrication involves synthesizing MoS₂ and coating Pd by DC sputtering technique. MoS₂ has been adopted for its high selectivity for H₂, wide operating temperature range, reliability, and low power consumption. Pd has high catalytic properties for H₂ and performs a H₂ adsorption mechanism through resistance transition. In this study, we propose a Pd-decorated MoS₂ structure and introduce the chemical resistance mechanism within the channel. The limit of detection (LOD), sensitivity and response time of the fabricated H₂ gas sensors are optimized and analyzed. Finally, the nanocomposites network based H₂ sensor can promote the utilization of various industries and discuss the issues in sensor applications.
