Abstract
A direct current atmospheric pressure glow discharge operated between a pin-type solid metallic electrode and the surface of a flowing solution, positively or negatively charged and serving as the flowing liquid anode or cathode, was used for synthesizing gold nanoparticles.
Highlights
Conventional methods for the synthesis of metallic nanoparticles (NPs) based on colloidal chemistry typically require many processing stages, including a cleaning step of the resulting nano uids with various solvents.[1]
By analyzing a scatter plot overlying the response for all 3 measurement series versus the randomized run order, it was revealed that the variability of the response between the treatments was higher than the variability of the response within the treatments
In the case of the plasma-reaction system sustained between the solid pin cathode and the flowing liquid anode (FLA), the model developed using the BBD-response surface regression (RSR) approach showed that the lmax of the localized surface plasmon resonance (LSPR) absorption band of the AuNPs produced using this system was affected by the ow rate of the FLA (A), the discharge current (B), the Au concentration in the solution of the FLA (C) and the gelatin
