Abstract

SnO nanoparticles have been synthesized by a novel route of a sol-gel method assisted with biomimetic assembly using L-leucine as a biotemplate. The microstructure of as-prepared SnO nanoparticles was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectra (FT-IR), and Brunner-Emmet-Teller (BET) measurements. The results demonstrated that the growth of SnO could be regulated by L-leucine at a high calcination temperature. The electrochemical performance of SnO was also measured as anodes for lithium-ion battery. It is a guidance for the growth regulation of SnO at high temperature to obtain SnO/C with nanosized SnO coated by a graphitic carbon.

摘要

通过一种新颖的溶胶-凝胶法路线，以L-亮氨酸作为生物模板辅助仿生组装合成了SnO纳米颗粒。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FT-IR）和布鲁诺-埃米特-泰勒（BET）测量对所制备的SnO纳米颗粒的微观结构进行了表征。结果表明，在高温煅烧温度下，L-亮氨酸可以调节SnO的生长。还测量了SnO作为锂离子电池阳极的电化学性能。这为高温下SnO的生长调控以获得具有被石墨碳包覆的纳米级SnO的SnO/C提供了指导。
