| 英文摘要 | Gold nanoparticles (AuNPs) are successfully synthesized via a facile and eco-friendly biosynthesis approach. Ginkgo biloba (G. biloba) leaf is an extract used as bio-aqueous solution for the preparation of the AuNPs. Photo-chemically, the G. biloba leaf plays dual roles wherein it serves as reducing and stabilizing agent. Through this approach, the use of toxin-induced chemical is completely avoided making the approach a green chemistry. Several synthetic parameters such as reactant concentration, media pH, reaction time and temperature are optimized which in turn enables the formation of AuNPs with uniform size. Various analytical techniques including scanning electron microscope (SEM), high resolution-transmission electron microscopic (HRTEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) spectroscopy, fringe spacing and selected area diffraction (SEAD) pattern, and dynamic light scattering (DLS) are used for AuNPs characterization. The AuNPs exhibit cubic structure and spherical shape with average size of 18.95 +/- 5.95 nm. The homemade AuNPs show promises in the catalytic decolorization of azo-dyes in the presence of sodium borohydride (NaBH4). In addition, the AuNPs show appreciable sensitivity for the detection of Cr(VI) with a detection limit found to be 0.1-0.8 mu M. This study is expected to spur further works on the use of metal nanoparticle for environmental pollution remediation. |
