Abstract

The functionalization of silicon nanoparticles by thermally induced hydrosilylation in a one-pot process is reported. In contrast to the commonly applied thermally induced hydrosilylation, the process described here is carried out in the presence of hydrofluoric acid as a second phase and therefore proceeds at a lower conversion temperature. The surface functionalization of silicon nanoparticles was analyzed by IR, 13C CPMAS NMR, EELS, and TGA techniques. The applied procedure resulted in functionalized silicon nanoparticles with good chemical and thermal stability.

摘要

报道了通过一锅法热诱导硅氢化反应实现硅纳米颗粒的功能化。与常用的热诱导硅氢化反应不同，此处描述的过程是在氢氟酸作为第二相存在的情况下进行的，因此在较低的转化温度下进行。通过红外光谱、13C交叉极化魔角旋转核磁共振、电子能量损失谱和热重分析技术对硅纳米颗粒的表面功能化进行了分析。所采用的方法得到了具有良好化学和热稳定性的功能化硅纳米颗粒。
