Abstract

In this research, we explore a highly sensitive chemiresistive hydrogen gas sensor based on Pd-decorated MoS 2 nanosheets deposited on yolk–shell (SiO 2 –TiO 2 ) nanospheres. This novel architecture was synthesized using a two-step facile hydrothermal method. The sensor shows a response of 317.3 towards 10,000 ppm hydrogen at 30 °C under a 9 V bias, with response and recovery times of 78 s and 39 s, respectively. The synergistic effect of Pd nanoparticles and MoS 2 deposited on the yolk–shell structure enhances the sensor performance and confirms its capability for real-world hydrogen sensing applications.
