Abstract
Systems and methods using engineered nanofiltration layers to facilitate acceleration of palladium nanowire hydrogen sensors. The sensors include a metal-organic framework (MOF) assembled on palladium (Pd) nanowires (NWs) for highly selective and ultra-fast H2 molecule detection.
Claims8
A bi-layer nanowire based hydrogen sensor, comprising:
- a plurality of palladium nanowires patterned onto a glass substrate, and
- a metal-organic framework (MOF) assembled on the plurality of nanowires, wherein a plurality of polyhedron particles of Zn based zeolite imidazole framework (ZIF-8) are deposited on the glass substrate and the surface of the palladium nanowires, wherein the plurality of polyhedron particles of Zn based zeolite imidazole framework (ZIF-8) are deposited directly on the glass substrate and the nanowires.
