SnO2 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 SnO2 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 SnO2 could be regulated by L-leucine at a high calcination temperature. The electrochemical performance of SnO2 was also measured as anodes for lithium-ion battery. It is a guidance for the growth regulation of SnO2 at high temperature to obtain SnO2/C with nanosized SnO2 coated by a graphitic carbon.

L-亮氨酸模板化SnO2纳米颗粒的仿生组装及其锂存储特性

SnO2 纳米颗粒已通过溶胶-凝胶法的新途径合成，辅助仿生组装，使用 L-亮氨酸作为生物模板。通过 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 Brunner-Emmet-Teller (BET) 测量表征所制备的 SnO2 纳米粒子的微观结构。结果表明，在高煅烧温度下，L-亮氨酸可以调节 SnO2 的生长。SnO2 的电化学性能也作为锂离子电池的负极进行了测量。用石墨碳包覆纳米尺寸的 SnO2 获得 SnO2/C，是对 SnO2 在高温下的生长调控的指导。
