Synthesize rGO-AG NPs by Pulse Laser Ablation in Less Pulse Energy and Ablation Time

Abstract

The rGO-Ag NPs have been synthesized successfully by pulse laser ablation PLA as a considered to be environmentally friendly and free of residues from chemical reactions. The high purity silver plate (99.9%) was immersed in the prepared graphene oxide solution and irradiated with the Nd-YAG laser at wavelength 1064 nm, energy 160 mJ, repetition rate 6 Hz , 10 ns pulse width and ( 200,300,400,500,600) pulses (ablation time) , to obtain silver nanoparticles anchored on the reduced graphene oxide sheets forming the nanocomposite rGO-Ag NPs. The nanocomposite rGO-Ag NPs were analysis by UV-Visible spectroscopy, (FTIR) Fourier Transform Infrared spectroscopy, X-ray diffraction (XRD), (AFM) Atomic force microscopy and (SEM) scanning electron microscope.
The results have shown the graphene oxide has a reduction as confirmed by UV-VIS, XRD and FTIR and the AFM, SEM studies confirmed the presence of silver particles in nanoscale and anchored on the reduced graphene oxide sheets.
