Nanofibrous Nanomatrix for One Dimensional Arrangement of Gold Nanoparticles |
| 초록 |
This contribution reports the photo-catalytic synthesis of gold nanoparticles (AuNPs) using poly(vinyl alcohol) (PVA) as a radical scavenger for one dimensional arrangements of AuNPs. With the optimization of the particle and scavenger concentration it was one dimensionally arranged on electrospun MgTiO3 ceramic nanofibers by “on substrate” irradiation. Initially, electrospun MgTiO3/poly(vinyl acetate) hybrid nanofibers were calcined at 650 ˚C to obtain phase pure MgTiO3 nanofibers 100-150 nm diameters. Fibers were immersed in an aqueous solution of HAuCl4 with PVA followed by photoreduction at λ~365 nm to get a novel Au-MgTiO3. The composites were analyzed by the SEM and TEM exhibiting strong diffractions correspond to Au (111), (200) planes.
