Novel ferromagnetic nanomaterials for gas sensing applications

Hydrogen is a key option for climate-friendly energy production but its use is severely limited by extreme flammability making advance hydrogen sensing technologies critical. We propose a new Hydrigen sensor based on a novel magneto-electronic approach. Completion of the project will generate knowledge resulting in the development of new technologies that will enable economic growth associated with “clean” energy and enhance quality of life in Australia.

We are exploring a new paradigm for hydrogen gas-sensing which takes advantage of the unique properties of ferromagnetic nanostructures interfaced with Palladium. Hydrogen uptake in hybrid Palladium/ferromagnetic nanostructures wherein hydrogen leads to significant changes in the magnetic properties of the devices. A new generation of high-sensitivity, fire-safe, non-contact hydrogen sensors will follow from this project.

This project combines nanofabrication, advanced magnetic characterisation as well as theoretical investigations.  It addresses the National Research Priority “Maximise Australia’s competitive advantage in critical sectors”. An important feature of this project is that it brings together a multidisciplinary team of leading international experts.
