Waste frying palm oil was used as reducing agent in synthesizing Sliver Nanoparticles<br />

(AgNPs) using wet chemical method. The reaction temperatures in the range of 40 ºC<br />

to 100 ºC were found to be directly proportional to yield of AgNPs. The AgNPs were<br />

characterized using Uv-Visible spectrophotometer, FTIR spectroscopy, XRD and SEM.<br />

The formation of AgNPs was notified by the presence of yellowish-brown colour and<br />

supported by the obtained SPR peak in the range of 400 to 420 nm. Based on FTIR<br />

spectroscopy, the waste frying palm oil acted as stabilizing agent. The main diffraction<br />

peaks obtained from XRD analysis established the crystalline nature of the AgNPs. The<br />

analysis of SEM showed the presence of AgNPs with spherical shape and size in the<br />

range of 1-100 nm. The result using Uv-Visible spectrophotometer showed absorbance<br />

intensities of Methyl Orange dye decreases as reaction time increases proved the<br />

catalytic activity of synthesized AgNPs.<br />
