Title: Surfactant-free fabrication of Cu{sub 2}O nanosheets from Cu colloids and their tunable optical properties

Abstract

Novel sheetlike Cu{sub 2}O two-dimensional (2D) nanoarchitectures were successfully synthesized via a copper nanoparticle-mediated process for the first time. Uniform and nearly monodisperse Cu nanocolloids were firstly synthesized by disproportionating reaction of Cu{sup +} at the surfactant-free ambient conditions, and Cu{sub 2}O nanosheets were subsequently synthesized by choosing ethanol solvent agent to limit the oxidized processes of Cu nanocolloids. The synthesized products were systematically studied by X-ray powder diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UV-vis absorption spectra. It was demonstrated that the solvent agent of ethanol played key roles in the formation of the as-synthesized nanosheets. By choosing the different solvent agents to limit the oxidized processes, Cu{sub 2}O nanospheres and nanocubes can be selectively synthesized accordingly. - Graphical abstract: Novel sheetlike Cu{sub 2}O 2D nanoarchitectures were successfully synthesized. It was demonstrated that the solvent agent of ethanol played key roles in the formation of the as-synthesized nanosheets.
