The near-spherical AgCl micro-crystals were prepared by an ionic liquids-assisted hydrothermal method. The influence of ionic liquids (C(x)MimCl x = 4, 8, 12, 16) on (001) facet growth of AgCl was studied systemically. The composition of the as-prepared samples was characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA) and FTIR spectra. The morphological structures were characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Based on experimental data and the classical crystal growth theory, a plausible growth mechanism of the near-spherical AgCl was proposed. The plasmonic photocatalyst Ag@AgCl prepared from the near-spherical AgCl showed higher activity than that of cubic morphologies.
近球形的 AgCl 微晶体是通过离子液体辅助水热法制备的。系统研究了离子液体（C(x)MimCl，x = 4、8、12、16）对 AgCl（001）面生长的影响。通过 X 射线衍射（XRD）、热重分析（TGA）和傅里叶变换红外光谱（FTIR）对所制备样品的组成进行了表征。通过扫描电子显微镜（SEM）和原子力显微镜（AFM）对形态结构进行了表征。根据实验数据和经典晶体生长理论，提出了近球形 AgCl 的生长机制。由近球形 AgCl 制备的等离子体光催化剂 Ag@AgCl 的活性高于立方形态。
