Tungsten disulfide few-layer film, an outstanding full solar spectrum photocatalyst

For applications in electrodes, energy storage devices and photoelectrochemical cells

Overview
Related Products

Few-layer tungsten disulfide (WS₂, CAS number 12138-09-9) film has a 2D-layered structure with a narrow indirect bandgap of of 1.35 eV. In contrast, the monolayer film possesses a direct bandgap of 2.1 eV.

WS₂ few-layer films possess very high NIR light photocatalytic activity. They also have strong UV and visible light photocatalytic activity, making them a valuable and outstanding full solar spectrum photocatalyst.

Applications

Due to its distinctive electron configuration and high specific surface area, few-layer tungsten disulfide nanosheets have potential applications in electrodes and energy storage devices, supercapacitors, and photoelectrochemical cells as a catalyst for hydrogen evolution reactions (HERs). With tunable electromagnetic absorption, it has practical applications against electromagnetic pollution. WS₂ is also a great potential candidate in photothermal therapy for the ablation of cancer cells, when NIR light is absorbed and converted into heat.

Synthesis

High-quality tungsten disulfide few-layer films were grown directly on the substrates (sapphire) via the chemical vapour deposition (CVD) method.

Usage

WS₂ few-layer films can be used for research purposes such as microscopic analysis, photoluminescence, and Raman spectroscopy studies. Few-layer WS₂ films can also be transferred to other substrates.
