| 초록 |
Silica hollow nanotubes were fabricated using vapor phase synthesis of silica precursor with hard template method. In particular, inner and outer surface of silica hollow nanotube were readily treated with various silanes and respective functional groups, such as amino group, carboxyl group, and fluorine group, were identified with FT-IR analyses. In addition, poly (acrylic acid) (PAA) was deposited inside the wall of silica hollow nanotube via vapor deposition polymerization, amplifying the carboxyl group. This PAA-functionalized silica hollow nanotube worked as a Pd catalyst support, catalyzing Heck-coupling reaction of aryl iodide and olefin. Selective functionalization technique on substrate can be further applied in various application, such as catalysis or drug delivery system. |
