We report an in situ liquid cell scanning transmission electron microscopy (STEM) study of the heterogeneous deposition of palladium (Pd) on spherical gold (Au) nanoparticles in solution. The dynamic processes observed here revealed different behaviors of Pd deposition on Au nanoparticles. Under irradiation by an energetic electron beam, Pd was reduced and selectively deposited on Au nanoparticles through the island deposition mode. The deposition processes were accompanied with structural relaxation and surface migration of the Pd islands, and the size of the Au-Pd composite particles showed oscillatory growth behavior. In contrast, the Pd coverage on Au increased monotonically. In addition, we also captured the formation of Pd clusters through homogeneous nucleation and growth, and the subsequent coalescence of Pd clusters with islands on the Au-Pd heterostructures. The associated heterogeneous deposition mechanisms were proposed and quantitatively analyzed. The shapes and structures of the Au-Pd composite particles were characterized by highresolution transmission electron microscopy (HRTEM), which revealed the deposited Pd on the Au spherical nanoparticles was polycrystalline and contained several Pd crystallites with random orientations. The results presented here will serve as an important reference to understand heterogeneous growth in liquid solutions.
