一般說明

氯化钨(VI)是一种高反应性结晶固体,常用于催化、钙钛矿太阳能电池和发光器件领域。它是一种抗磁性固体。但是,它具有很强的腐蚀性和氧化作用。

應用

氯化钨(VI)可用于:
  • 作为水热法合成钨纳米颗粒和Mo掺杂海胆状W18O49纳米结构的原料。Mo-W18O49电催化剂对析氢反应(HER)表现出优异的电催化活性。通过将Mo掺杂到富含缺陷的W18O49超薄纳米线中,证明它是光催化N2固定合成氨的极佳选择。
  • 以高分子量两亲性嵌段共聚物为结构导向剂,合成孔径为11 nm的结晶性介孔WO3。这些材料在H2S气体传感方面表现出色。
  • 水热合成法制备二硫化钨和WS2/还原氧化石墨烯(WS2/rGO)纳米片。WS2/rGO纳米片在析氢反应中表现出优异的电催化活性。
  • 生产WS2-纳米花@rGO和氮掺杂碳球@WS2复合材料作为负极材料,增强锂离子电池的电极性能。
  • 作为掺杂剂,制造性能增强的钙钛矿太阳能电池用TiO2致密层。
  • 作为催化剂制备具有微胶囊的自修复环氧树脂复合材料。
  • 作为叔烷基酰胺转酰胺反应的催化剂。

Oxidative chemical vapour deposition of (5,15-diphenylporphyrinato)nickel(II) (NiDPP) with iron(III) chloride as oxidant yielded a conjugated poly(metalloporphyrin) as a highly coloured thin film, which is potentially useful for optoelectronic applications. This study clarified the reactive sites of the porphyrin monomer NiDPP

Tungsten Disulfide (WS2) is considered to be a promising Hydrogen Evolution Reaction (HER) catalyst to replace noble metals (such as Pt and Pd). However, progress in WS2 research has been impeded by the inertness of the in-plane atoms during HER.
