Active hydrogen enables the interfacial synthesis of metal alloy nanocrystals

Conventional synthesis of noble/non-noble metal alloy nanocrystals lacks control over metal co-reduction. An interfacial co-reduction strategy involving active hydrogen is developed that overcomes the difference in the reduction potential of the metals to enable the controlled synthesis of alloy nanostructures with precise and broadly tunable compositions.
