Duan H Yan N Yu R Chang CR Zhou G Hu HS Rong H Niu Z Mao J Asakura H Tanaka T Dyson PJ Li J Li Y 2014 Despite significant advances in the fabrication and applications of graphene-like materials, it remains a challenge to prepare single-layered metallic materials, which have great potential applications in physics, chemistry and material science. Here we report the fabrication of poly(vinylpyrrolidone)-supported single-layered rhodium nanosheets using a facile solvothermal method. Atomic force microscope shows that the thickness of a rhodium nanosheet is <4 Å. Electron diffraction and X-ray absorption spectroscopy measurements suggest that the rhodium nanosheets are composed of planar single-atom-layered sheets of rhodium. Density functional theory studies reveal that the single-layered Rh nanosheet involves a δ-bonding framework, which stabilizes the single-layered structure together with the poly(vinylpyrrolidone) ligands. The poly(vinylpyrrolidone)-supported single-layered rhodium nanosheet represents a class of metallic two-dimensional structures that might inspire further fundamental advances in physics, chemistry and material science. application/pdf https://sonar.ch/global/documents/225739 eng info:eu-repo/semantics/altIdentifier/doi/10.1038/ncomms4093 info:eu-repo/semantics/altIdentifier/pmid/24435210 info:eu-repo/semantics/openAccess Nature communications. - 2014 General Biochemistry, Genetics and Molecular Biology General Physics and Astronomy General Chemistry Ultrathin rhodium nanosheets. http://purl.org/coar/resource_type/c_6501
