二维（2D）过渡金属二硫属化物（TMDC）因其优异的性能而成为开发纳米电子、催化、能源存储和环境相关领域应用的完美平台。然而，高质量2D TMDC 的低成本、批量生产仍然是现有合成策略的巨大挑战。在此，我们提出了一种可扩展的化学气相沉积（CVD）方法，通过使用天然丰富的水溶性和可回收的 NaCl 晶体粉末作为模板，批量生产高质量的 MoS2 纳米片粉末。凭借所生成的产品在水中的优异分散性，通过简便的水溶解过滤过程获得了高质量的 MoS2 纳米片粉末。探索了可扩展合成策略的内部机制。 MoS2纳米片粉末还分别作为析氢反应（HER）和有机染料吸附中的催化剂或吸附剂的应用。这项工作将为粉状TMDCs在能源和环境相关领域的大规模生产和应用铺平道路。
Two-dimensional (2D) transition metal dichalcogenides (TMDCs) have emerged as perfect platforms for developing applications in nano-electronics, catalysis, energy storage and environmental-related fields due to their superior properties. However, the low-cost, batch production of high-quality 2D TMDCs remains a huge challenge with the existing synthetic strategies. Herein, we present a scalable chemical vapor deposition (CVD) approach for the batch production of high-quality MoS2nanosheet powders, by using naturally abundant, water-soluble and recyclable NaCl crystal powders as templates. The high-quality MoS2nanosheets powders are achieved by a facile water dissolution-filtration process, by virtue of the excellent dispersibility of the as-grown products in water. The internal mechanism for the scalable synthesis strategy is explored. The applications of the MoS2nanosheets powders are also demonstrated as catalysts or adsorbents in hydrogen evolution reaction (HER) and organic dyes adsorption, respectively. This work should hereby pave ways for the mass production and application of powdery TMDCs in energetic and environmental related fields.
