dc.description.abstract | A half-pipe palladium nanotube network (H-PdNTN) structure was developed for high-performance hydrogen (H-2) sensor applications. To fabricate the sensor, suspended poly(vinyl alcohol) (PVA) nanofiber bundles were electrospun on a conductive substrate, followed by a palladium (Pd) deposition on top of the PVA nanofiber bundles. Then, Pd-deposited PVA nanofibers were transferred to a host substrate, and the PVA nanofiber templates were selectively removed. Various material analyses confirmed that the PVA nanofibers were successfully dissolved leaving a half-pipe-shaped Pd nanotube network. The fabricated Pd nanotube-based sensors were tested for H-2 responses with different gas concentrations. The 4 nm thick sensor showed the highest response (Delta R/R-0) to H-2 gas. Platinum (Pt) decoration of the sensor showed an improved response speed compared to that of the pristine sensor via the catalytic function of Pt. Additionally, the sensor exhibited good H-2 selectivity against other interfering gases. The H-PdNTN H-2 sensor provides a facile and cost-effective way to fabricate high-performance H-2 sensors. | - |
