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

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 explains for the first time how Au makes such a difference, which will be valuable for fine-tuning further improvements.
