| Abstract: | Functionalization of Silicon Nanoparticles with Hydrogen Fluoride and Olefins Silicon nanoparticles (Si‐NPs) from a hot wall reactor (size: 50–300 nm) were freed of surface‐bound SiOx with anhydrous HF, leaving H‐terminated Si‐NPs. Thermally induced hydrosilylation with 1‐octene lead to the formation of surface bound octyl layers. Using anhydrous HF instead of 40 % hydrofluoric acid leads more efficiently to alkylated Si‐NPs. |
