A facile and cost-effective method to prepare defect-rich MoS nanosheets is developed via an electrochemical exfoliation process. By using bucket-like metallic titanium mesh both as inert anode and container for MoS powders, defect-rich thin MoS nanosheets can be fast exfoliated from the bulk powders in aqueous sodium sulfate electrolyte under positive potentials. The as-obtained MoS nanosheets exhibit excellent cycling capability, high specific capacity, and superior rate performance for lithium storage. Furthermore, it provides a novel and effective method to exfoliate insulative or semiconductive layer-structured bulk powders into defect-rich 2D nanosheets.
通过电化学剥离工艺，开发了一种简便且经济高效的方法来制备富含缺陷的 MoS 纳米片。使用桶状金属钛网作为惰性阳极和 MoS 粉末的容器，在正电势下，富含缺陷的薄 MoS 纳米片可以从块状粉末在硫酸钠水溶液中快速剥离。所获得的 MoS 纳米片表现出优异的循环性能、高比容量和优异的储锂倍率性能。此外，它为剥离绝缘或半导体层状块状粉末成富含缺陷的二维纳米片提供了一种新颖有效的方法。
