Growth of two-dimensional rhenium disulfide (ReS2) nanosheets with a few layers at low temperature

Abstract

We present an efficient growth process of rhenium disulfide (ReS2) nanosheets with a few layers at relatively low temperature under ambient pressure. Highly single-crystalline two-dimensional ReS2 nanostructures are obtained from a direct chemical reaction between rhenium atoms (Re) originating from the decomposition of ReCl3 and sulfur atoms (S) on a SiO2 substrate under helium (He) gas flow at 450 °C. The synthetic approach for the ReS2 nanosheets exhibits several favorable features: it is simple, cost-effective, and versatile for the development of new functional platforms toward highly single-crystalline 2D layered materials. © 2017 The Royal Society of Chemistry.
