提出了一种通用的基于溶液的方法，利用一步比例还原-氧化反应从二维层状硫属化合物中脱出零价锡和铜。插入的零价金属与溶解在丙酮中的高氧化态金属阳离子（Sn4+和Cu2+）发生反应。这种化学反应被证明适用于各种具有不同形态和结晶度的层状硫属化合物。从MoS2、MoSe2、NbSe2和WS2粉末以及Bi2Se3、In2Se3和GeS纳米带中分离出铜和锡。这种化学反应实现了从二维层状硫属化合物中去除零价锡和铜的一般途径。
A general solution-based approach to deintercalate zero-valent tin and copper from two-dimensional layered chalcogenides is presented using a one-step comproportionation reduction–oxidation reaction. The reaction is performed between the intercalated zero-valent metal and high oxidation state metal cations (Sn4+ and Cu2+) dissolved in acetone. This chemistry is shown to work for a variety of layered chalcogenides with differing morphologies and crystallinity. Copper and tin are deintercalated from powders of MoS2, MoSe2, NbSe2, and WS2 and crystalline nanoribbons of Bi2Se3, In2Se3, and GeS. This chemistry achieves a general route to remove zero-valent tin and copper from 2D layered chalcogenides.
