Abstract
Developing sensitive hydrogen gas sensors is crucial for detecting and managing hazards in storage, transport, and leakages. While metal oxide gas sensors (MOX) suffer from poor selectivity and high temperatures, attention has shifted to two-dimensional materials like tungsten disulfide (WS2). Howev-er, bare WS2 sensors face limitations like slow response-recovery times and low sensitivity. Function-alizing TMDs with noble metal nanoparticles, notably Pd, enhances sensor performance. This study presents a highly sensitive Pd-decorated WS2 composite based sensor for room temperature (RT) H2 sensing, with a remarkable response of 55% (Pd quantity (3 mg).
