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

• Hollow Ag-Pd nanoparticles have potentially highcatalyticperformance owing to their larger surface area compared to their correspondingsolid nanoparticles. We successfully fabricated hollow Ag-Pdalloy nanodendrites and nanoboxes by using different Pd precursors(H2PdCl4 and Pd(acac)(2)) to achievelarge surface area nanoboxes. Interestingly, the use of a H2PdCl4 precursor led to the formation of hollow nanodendritestructures, whereas the slower reduction of Pd(acac)(2) ledto the formation of hollow nanoboxes. The microstructure and chemicalcomposition of Ag-Pd nanoparticles and properties of theirgrowth solutions were investigated by transmission electron microscopy,energy-dispersive X-ray spectroscopy, and ultraviolet-visiblespectroscopy.
