Electrical conduction and sensing properties of contacted CNTs after MOF synthesis — •Marvin J. Dzinnik¹, Adrian Hannebauer², Feriel Friha¹, Andreas Schaate², and Rolf J.

Metal-organic frameworks (MOFs) are a versatile sensor material: they are tunable, highly porous, and can be precisely grown on carbon nanotubes (CNTs).[1]

Here, we investigate how UiO-66 MOF growth affects single nanotubes. We performed DC measurements on contacted multi-walled carbon nanotubes (MWCNTs) before and after UiO-66 synthesis. We observe pronounced changes in both magnitude and character of the electrical response, indicating a strong interaction between MWCNT and MOF. AC measurements show a linear response to ethanol vapor up to 40 000 ppm, suggesting that single MWCNT-MOF hybrids are promising, tunable gas-sensing elements.
