论文摘要
在过去的十年中,材料社区一直在探索具有独特物理和化学性能的新2D材料(石墨烯,Metallene,TMD,TMC,MXENE等)。最近,已经提出了一个新的2D材料,即所谓的2D硅酸盐。预计它们具有令人兴奋的特性(例如高催化活性,压电性和2D磁性)。在当前的工作中,我们演示了一种从选定矿物(例如Diopside(D))合成大规模2D硅酸盐的通用方法。使用不同的实验技术来确认2D结构的存在(命名为2D-silicates)。 DFT模拟还用于深入了解结构特征和能量收集机制(挠性响应产生高达10 V的电压)。当前的方法是完全一般的,可以用于大规模合成2D硅酸盐及其衍生物,其大规模合成是难以捉摸的。
In the last decade, the materials community has been exploring new 2D materials (graphene, metallene, TMDs, TMCs, MXene, among others) that have unique physical and chemical properties. Recently, a new family of 2D materials, the so-called 2D silicates, have been proposed. They are predicted to exhibit exciting properties (such as high catalytic activity, piezoelectricity, and 2D magnetism). In the current work, we demonstrate a generic approach to the synthesis of large-scale 2D silicates from selected minerals, such as Diopside (d). Different experimental techniques were used to confirm the existence of the 2D structures (named 2D-d-silicates). DFT simulations were also used to gain insight into the structural features and energy harvesting mechanisms (flexoelectric response generating voltage up to 10 V). The current approach is completely general and can be utilized for large-scale synthesis of 2D silicates and their derivatives, whose large-scale syntheses have been elusive.
