Research on preparation of 2D Cu nanomaterials

Abstract

Abstract Recently, metal nanosheets have been a promising material for application in nano-electrical devices. This study describes a chemical reduction preparation method of large-area Cu nanosheets in a facile condition using copper sulfate as source and glucose as reductant. The morphology and phase analysis of the synthesized copper nanosheets are measured by scanning electron microscope (SEM) and X-ray electron diffraction (XRD). The influences of several experimental parameters on the morphology of the products such as reducing agent and reaction temperature are investigated. It is found that by changing the molar ratio of copper ion to reductant, the thickness of copper nanosheets can be controlled. The obtained productions demonstrate excellent electrical conductivity.
