Hydrothermal Synthesis and Enhanced Corrosion Inhibition Activity of CdS QDs toward Zn Surface

The hydrothermal method was used to synthesize hexagonal 3-5 nm CdS QDs with Delonix elata leaves aqueous extract as a capping agent. The synthesized CdS QDs were characterized by FTIR, UV-Vis, XRD, FESEM spectroscopy. The anticorrosion activity of CdS QDs coated Zn plate was exanimated under 1 M HCl, 6 M KOH, 3.5% NaCl electrolytic medium. The best corrosion resistance was achieved through the application of the CdS QDs coating on the Zn metal surface.
