In the present communication, the atomic structure and coordination of surface adsorbed species on Nb2C MXene is investigated over time. In particular, the influence of the Nb adatoms on the structural stability and oxidation behavior of the MXene is addressed. This investigation is based on the plane-view geometry observations of single Nb2C MXene sheets by a combination of atomic-resolution scanning transmission electron microscopy (STEM), electron energy loss spectroscopy (EELS) and STEM image simulations.
在本通讯中，研究了在时间推移过程中，Nb2C MXene 表面吸附物种的原子结构和配位情况。特别地，研究了 Nb 原子吸附对 MXene 结构稳定性和氧化行为的影响。这项研究基于原子分辨扫描透射电子显微镜（STEM）、电子能量损失谱（EELS）和 STEM 图像模拟的组合，对单个 Nb2C MXene 片的平面视图几何形状进行了观察。
