황화 텅스텐 C화학적 특성, 용도, 생산
개요
Few-layer?tungsten disulfide (WS2) 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.제조 방법
Synthetic?- Chemical Vapour Transport (CVT)주요 응용
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.
화학적 성질
Grayish-black solid. Mp above 1480C, can lubricate at temperatures above 2400F (1316C). Attacked by fluorine and hot sulfuric and hydrogen fluoride.용도
Tungsten sulfide is used as a component of catalysts for hydrotreating of crude oil, hydrodesulfurization and hydrodenitrification reactions. It finds application as solid-state secondary lithium battery cathodes and other electrochemical devices. It is found that it forms inorganic nanotubes, which is better reinforcing agents than carbon nanotubes. Tungsten sulfide addition to epoxy resin improves adhesion, fracture toughness and strain energy release rate.황화 텅스텐 준비 용품 및 원자재
