Exploitation of de-oiled jatropha waste for gold nanoparticles synthesis: A green approach
A novel single step green-synthesis route has been developed for the synthesis of gold nanoparticles using aqueous extract of de-oiled jatropha waste (DJW). DJW, a second stage waste, was adopted as a reducing agent to reduce HAuCl4. Different optimal parameters such as ratio of HAuCl4(aq)/DJW(aq),...

A novel single step green-synthesis route has been developed for the synthesis of gold nanoparticles using aqueous extract of de-oiled jatropha waste (DJW). DJW, a second stage waste, was adopted as a reducing agent to reduce HAuCl4. Different optimal parameters such as ratio of HAuCl4(aq)/DJW(aq), reaction temperature and pH effects were also studied to fine-tune the shape of the gold nanoparticles (AuNPs). The resultant AuNPs were characterized by UV–visible spectrometry, Transmission electron microscopy, Selected area electron diffraction, Powder X-ray diffraction and Fourier transform infrared spectroscopy.
