Abstract

The present study reports the green synthesis of gold nanoparticles (AuNPs) in which palm oil leaf extract was used as reducing agent to reduce gold ions in chloroauric acid into AuNPs. Palm oil leaf is chosen because it possesses anti-oxidant properties, under-utilised and considered as a major waste in palm oil industry. The synthesized AuNPs were characterized using UV-Vis spectroscopy, Transmission Electron Microscopy (TEM) and Fourier Transform Infrared Spectroscopy (FTIR). The effect of varying concentration of chloroauric acid, volume ratio, temperature and reaction time towards the morphology and size of synthesized AuNPs were analyzed. TEM imaging done of the sample confirms the presence of polydispersed AuNPs with mean diameter of 29.49 nm. In addition, the synthesized AuNPs composed of hexagonal and orthorhombic crystalline structures. Bio-molecules in palm oil leaf extract such as protein, flavonoids or phenols that contain abundant of C=O, N-H or O-H groups might be accountable for the reductions of gold ions into AuNPs because decrease in intensity of gold solution was observed at 3349.79 cm−1.
