As the
surface energies of 111, 112, and 110 planes are known to be 1.6055, 1.8642, and 1.9342 J/m2[24, 26], it appears that the 111-planar surface is more favorable thermodynamically. Figure 6 Crystal structure of Ag nanosheets. (a) BF TEM image of a Ag nanosheet, (b and c) FFT images of the marked square areas in (a), respectively. Conclusions We developed a find more facile, one-step, low-cost, and large-scale method of fabricating single-crystalline Ag nanosheets with controllable thickness without any templates, capping agents, or sacrificial seed materials. The growth of nanosheets occurred in three stages: polygonal island formation, facetted nanowire growth, and planar growth of nanosheet coherent with the facetted nanowire. ON-01910 purchase The nanosheets with 111-planar surfaces and 112-edge planes had a controllable thickness depending upon the deposition frequency and reduction/oxidation potentials. The present method is expected to contribute to the development of environment-friendly and low-cost electrochemical synthesis of nanomaterials. Acknowledgments This work was supported
