Abstract

Visible light active hydrogen sensor can operate at ambient temperatures with enhanced performance making them a promising candidate for real-world applications. In this study, such sensor has been fabricated that employ heterojunctions containing Pd nanoparticles (NPs) decorated on TiO2 nanospheres (Pd-decorated TiO2 NS) using facile chemical methods. The sensor shows a response of 100.88% towards hydrogen with fast response and recovery (77 s and 470 s, respectively) at 30 ℃ under 565 nm visible light conditions and a voltage bias of 0.5 V.
