文摘
- •
Nanoporous silver is obtained via dealloying of Cu3Si phase from the crystalline precursor.
- •
Bulk thin middle layer of nanoporous foil reinforces its mechanical integrity.
- •
Pores of < 100 nm and high surface area of 5 m2/g is advantageous for catalytic applications.
- •
Designed material is successfully tested for applications in Direct Ammonia-Borane Fuel Cell as porous anodic catalyst.
- •
Materials show very high stability and lower onset voltage comparing to H2-fed fuel cell.
