Green synthesis of gold nanoparticles using aspartame and their catalytic activity for p-nitrophenol reduction
We demonstrated a facile and environmental-friendly approach to form gold nanoparticles through the reduction of HAuCl4 by aspartame. The single-crystalline structure was illustrated by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The energy-dispersive X-ray spectroscopy (EDS) and Fourier transform infrared (FTIR) results indicated that aspartame played a pivotal role in ...
متن کاملIn situ recyclable gold nanoparticles using CO2-switchable polymers for catalytic reduction of 4-nitrophenol.
CO(2)-switchable gold nanoparticles (AuNPs) were prepared by functionalizing AuNPs with CO(2)-switchable polymers. Their dispersion-re-dispersion in and separation from aqueous solution can be easily and reproducibly adjusted by CO(2) bubbling through and removal from the solution, enabling unique CO(2) controllable, efficient in situ recycling of NPs. As compared to non-functionalized AuNPs, t...
متن کاملGlucomannan-mediated facile synthesis of gold nanoparticles for catalytic reduction of 4-nitrophenol
A facile one-pot approach for synthesis of gold nanoparticles with narrow size distribution and good stability was presented by reducing chloroauric acid with a polysaccharide, konjac glucomannan (KGM) in alkaline solution, which is green and economically viable. Here, KGM served both as reducing agent and stabilizer. The effects of KGM on the formation and stabilization of as-synthesized gold ...
متن کاملSize effect of gold nanoparticles in catalytic reduction of p-nitrophenol with NaBH4.
Gold nanoparticles (Au NPs) were prepared by reducing HAuCl4 with NaBH4. Their average particle sizes could be tuned in the range of 1.7 and 8.2 nm, by adjusting the amount of NaBH4 used during synthesis. The obtained Au NPs (colloids) were then loaded onto a commercial Al2O3 support to prepare Au/Al2O3 catalysts with tunable Au particle sizes. An optimal pH value (5.9) of the Au colloid soluti...
متن کاملCatalytic reduction of 4-nitrophenol with gold nanoparticles synthesized by caffeic acid
In this study, various concentrations of caffeic acid (CA) were used to synthesize gold nanoparticles (CA-AuNPs) in order to evaluate their catalytic activity in the 4-nitrophenol reduction reaction. To facilitate catalytic activity, caffeic acid was removed by centrifugation after synthesizing CA-AuNPs. The catalytic activity of CA-AuNPs was compared with that of centrifuged CA-AuNPs (cf-CA-Au...
