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.
Claims11
A method for forming a bi-layer nanowire based hydrogen sensor, comprising the steps of:
- patterning a plurality of palladium nanowires on a bi-layer nanowire based hydrogen substrate;
- and
- immersing the substrate patterned with the plurality of palladium nanowires in a methanol (MeOH) solution including Zn precursors (Zn(NO3)2·6H2O) and 2-methylimidazole (mIM), wherein ZIF-8 is assembled on both the plurality of palladium nanowires and the substrate by heterogeneous nucleation.
