We have developed an efficient strategy for the production of stable β-palladium hydride (PdH_0.43) nanocrystals with controllable shapes and remarkable stability. The as-synthesized PdH_0.43 nanocrystals showed impressive stability in air at room temperature for over 10 months, which has enabled the investigation of their catalytic property for the first time. The prepared PdH_0.43 nanocrystals served as highly efficient catalysts in the oxidation of methanol, showing higher activity than their Pd counterparts. These studies opened a door for further exploration of β-palladium hydride-based nanomaterials as a new class of promising catalytic materials and beyond.
