The morphology of the synthesized Ag/Pd nanostructures is observed to be that of regular triangular nanoplates with a hollow structure. The mean thickness of the side shells on hollow bimetallic nanoplates is found to be ~16.5 nm. As supported by the analysis of electrochemical quartz crystal microgravimetry, the mean deposition rate catalyzed by the prepared Ag/Pd triangular nanoshells is measured to be ~1.33 g/cm2s. The triangular alloy nanomaterials can be successfully used as activators and exhibit excellent activity in electroless nickel deposition.
