Abstract: In the last decade, there has been an increased interest in using palladium (Pd) nanostructures for hydrogen (H2) sensing devices. Nanostructured based sensors promise shorter response times and higher sensitivity due to their high surface-to-volume ratio. With this in mind, an anodic alumina membrane (AAM) Pd nanostructured based sensor has been developed and tested. The Solid State Reduction method used formed a combination of a thin film and nanowires in the AAM. The fabrication method and preliminary test results are discussed here.
