Although liquid mercury (Hg) has been known since antiquity, the formation of stable solid nano forms of Hg at room temperature has not been reported so far. Here, for the first time, we report a simple sonochemical route to obtain solid mercury nanoparticles, stabilized by reduced graphene oxide at ambient conditions. The as-formed solid Hg nanoparticles were found to exhibit remarkable rhombohedral morphology and crystallinity at room temperature. Extensive characterization using various physicochemical techniques revealed the unique properties of the solid nanoparticles of Hg compared to its bulk liquid metal phase. Furthermore, the solid nature of the Hg nanoparticles was studied electrochemically, revealing distinctive properties. We believe that solid Hg nanoparticles have the potential for important applications in the fields of electroanalytical chemistry and electrocatalysis.

室温下固体汞（Hg）纳米粒子的可持续存在及其应用

尽管液态汞（Hg）自古以来就已为人所知，但迄今为止尚未报道在室温下形成稳定的固态纳米形式的汞。在这里，我们首次报告了一种简单的声化学途径来获得固体汞纳米颗粒，并在环境条件下通过还原氧化石墨烯进行稳定。发现所形成的固体汞纳米颗粒在室温下表现出显着的菱面体形态和结晶度。使用各种物理化学技术进行的广泛表征揭示了汞固体纳米颗粒与其本体液态金属相相比的独特性质。此外，还对汞纳米粒子的固体性质进行了电化学研究，揭示了独特的特性。我们相信固体汞纳米粒子在电分析化学和电催化领域具有重要的应用潜力。
