Why gold-palladium alloys are better than palladium for hydrogen storage

11-Jul-2018

Materials that absorb hydrogen are used for hydrogen storage and purification, thus serving as clean energy carriers. The best-known hydrogen absorber, palladium (Pd), can be improved by alloying with gold (Au). New research led by The University of Tokyo Institute of Industrial Science explains ...
