Novel flake ‐ belt integrative silver (Ag) nanocrystals have been constructed for the first time by a facile one ‐ step reduction reaction. In the process, as a modulator, a trace amount of ethylenediaminetetraacetic acid disodium salt played an important role. According to the basic characterisation, a selective deposition and an epitaxial growth mechanism of the reduced Ag were used to explain the formation of the flake ‐ belt integrative structure. The high integration of a flake and belt in one particle is completely different from the stacked assembly of nanobelts and flakes. Interestingly, uniform Ag nanobelts were obtained by simply modulating experiments. This work provided a methodology to fabricate metal hierarchical nanoparticles and a new thinking on the growth of Ag nanocrystals.
