Abstract

Abstract We report on the fabrication of bi-dimensional alumina/palladium nanowire nano-architectures for hydrogen detection, storage and controlled release. This nanostructured material was fabricated by growing the palladium nanowires directly in the nanosized channels of nanoporous alumina membrane followed by atmospheric-plasma jet treatment to fabricate the interconnected surface structure mostly suitable for hydrogen-related applications such as controlled release and sensing. Several interesting properties are demonstrated, including high sensitivity levels (up to 0.1% of {H2} in air) and short response times. Large resistance response reaching 100% for 0.5% of {H2} in air makes it possible to use the fabricated sensors without complex and expensive amplifying circuits.
