TLDR
In this article, a multi-layer H 2 sensor includes a carbon nanotube layer, and a ultra-thin metal or metal alloy layer in contact with the carbon-naphase layer.Abstract:
A multi-layer H 2 sensor includes a carbon nanotube layer, and a ultra-thin metal or metal alloy layer in contact with the nanotube layer. The ultra-thin metal or metal alloy layer is preferably from 10 to 50 angstroms thick. An electrical resistance of the layered sensor increases upon exposure to H 2 and can provide detection of hydrogen gas (H 2 ) down to at least 10 ppm, The metal or metal alloy layer is preferably selected from the group consisting of Ni, Pd and Pt, or mixtures thereof. Multi-layered sensors and can be conveniently operated at room temperature.read more
