Optical hydrogen sensing beyond palladium
Hafnium and tantalum as effective sensing materials
The detection of hydrogen in a fast, efficient and accurate way is vital for its safe handling in industrial processes and in its use as an energy carrier. Thin film metal hydrides are able to probe the hydrogen pressure, often relying on a change of the optical properties of ...
Hydrogen detection is essential for its implementation as an energy vector. So far, palladium is considered to be the most effective hydrogen sensing material. Here we show that palladium-capped hafnium thin films show a highly reproducible change in optical transmission in re ...
This work deals with the thermodynamics of hydride formation in 3-D nanoconfined Mg. Two ensembles of nearly monodisperse Mg nanodots (NDs) with different diameters (60 and 320 nm), were grown by the template nanopatterning method, using ultra-thin alumina membranes (UTAMs) wi ...
