蛋壳膜原位生长PbS纳米颗粒及其机理初探

摘要

Flowerlike PbS nanoparticles were successfully in situ synthesizing on an eggshell membrane(ESM)by a home-made I-ons-exchange device at room temperature. X-ray diffraction (XRD),scanning electron microscopy(SEM)and fourier transform infrared spectroscopy ( FTIR) were used for identifying the presence of PbS nanoparticles on ESM. Furthermore, a growth mechanism of the PbS nano-materials on eggshell membrane was discussed.%基于双扩散原理,在室温条件下,利用活性蛋壳膜具有的特殊渗透功能,成功地在蛋壳膜的活性位点处原位生长出绣球花状的硫化铅纳米颗粒.用X-射线衍射仪(XRD)、扫描电子显微镜(SEM)和傅里叶变换红外光谱仪(FTIR)对硫化铅纳米颗粒的形貌和结构进行了表征,并对蛋壳膜上原位生长硫化铅纳米颗粒的生长机理进行了初步探讨.
