The Effect of the Pd Precursors on the Shape of Hollow Ag-Pd Alloy Nanoparticles Using Ag Nanocubes as Seeds.

ABSTRACT: Hollow Ag-Pd nanoparticles have potentially high catalytic performance owing to their larger surface area compared to their corresponding solid nanoparticles. We successfully fabricated hollow Ag-Pd alloy nanodendrites and nanoboxes by using different Pd precursors (H₂PdCl₄ and Pd(acac)₂) to achieve large surface area nanoboxes. Interestingly, the use of a H₂PdCl₄ precursor led to the formation of hollow nanodendrite structures, whereas the slower reduction of Pd(acac)₂ led to the formation of hollow nanoboxes. The microstructure and chemical composition of Ag-Pd nanoparticles and properties of their growth solutions were investigated by transmission electron microscopy, energy-dispersive X-ray spectroscopy, and ultraviolet-
