摘要

以牛血清蛋白(BSA)单层分子膜为有机模板, 通过氨气扩散促进前驱体溶液中的硫代乙酰胺水解, 在气液界面上制备了取向单一的PbS晶体. 并用扫描电子显微镜(SEM), 透射电子显微镜(TEM), X射线衍射(XRD)和X射线光电子能谱(XPS)对其进行了表征. 结果表明：利用该方法制备的PbS晶体为均匀分布的四方形颗粒, 沿(200)晶面取向生长并呈现单晶结构. 分析认为形成这种结构的主要原因是BSA分子与Pb2+之间的静电相互作用和空间几何结构的匹配. 本实验为制备具有特殊结构的无机晶体材料提供了一种可能的途径.

Abstract

Using a BSA monolayer as organic template, single oriented PbS crystals were prepared at the gas-liquid interface in the presence of kinetically controlled ammonia diffusion to promote hydrolysis of thiacetamide in the precursor solution. The crystals were characterized by means of scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscope (XPS), respectively. The results show that the crystals exhibit a regular square morphology and have a uniform size distribution. The crystals growing along the (200) plane have a single crystalline structure. The electrostatic interaction and the geometrical matching between the BSA molecules and Pb2+ ions are the main reason for the oriented growth along the (200) plane. This method provides a potential approach for growing inorganic crystals with special structural features.

Key words： BSA monolayer; ammonia diffusion; PbS single crystal; biomimetic mineralization
