General Description

Rhenium disulfide (ReS2) is a direct band gap semiconductor that has exhibited outstanding optoelectronic performance due to its weak interlayer coupling. Compared to black phosphorus (BP), ReSis a naturally-occurring yet extremely rare TMDC so it is environmentally stable which makes it an ideal candidate for applications in ambient conditions. ReS2 has been found to be a diamagnetic semiconductor, an n-type photovoltaic material with a 1.4 eV optical gap, and exhibits bi-axial optical and electrical properties.

Unlike most of the TMDCs, ReS2 has an unique structure with its in-plane 1D chains of Re atoms. These are arranged into linked parallelograms - forming Re4 “diamond” shapes along the b axis. Such a structure makes it an optically bi-axial material which shows exceptionally anisotropic electrical and optical behaviour for linearly-polarised light.

Rhenium Disulfide Powder
Rhenium Disulfide (ReS2) powder structure.


Exfoliated rhenium disulfide (ReS2) nanosheets are shown to have a strong near-infrared (NIR) absorbance, and could effectively be used in biomedical applications, such as CT imaging and chemo-photothermal cancer treatment. High-purity rhenium disulfide powder is great for obtaining ReS2 nanosheets by liquid exfoliation in mass production.

ReS2 nanosheets and nanoparticles are also used for the fabrication of field-effect transistors, energy storage devices (such as rechargeable batteries, photocatalytic and electrocatalytic hydrogen evolution reactions (HER).


Rhenium disulfide (ReS2powder is obtained via the CVT method, with a purity in excess of 99.995% achieved.


Rhenium disulfide (ReS2powder is suitable for liquid chemical exfoliation to prepare GeSe nanosheets and nanoparticles down to few-layer films. ReS2 powder is also used for preparation of mono-layer and few-layer films via chemical vapour deposition (CVD).
