Ultrasound-assisted microwave synthesis of CdS/MWCNTs QDs: A material for photocatalytic and corrosion inhibition activity

Semiconductor CdS/Multiwalled carbon nanotube quantum dots with crystallite size of 2–3 nm have been successfully synthesized by an ultrasound-assisted microwave method. The sap of opunica ficus-indica fruit is used as natural capping agent to enhance the quantum dot’s stability. The synthesized CdS...

Summary:Semiconductor CdS/Multiwalled carbon nanotube quantum dots with crystallite size of 2–3 nm have been successfully synthesized by an ultrasound-assisted microwave method. The sap of opunica ficus-indica fruit is used as natural capping agent to enhance the quantum dot’s stability. The synthesized CdS/MWCNTs QDs were characterized by XRD, UV–Visible, FT-IR, HR-TEM, DLS, TGA, DTA and XRF. The photocatalytic activity of the QDs was tested for the degradation of dye, pararosaniline under simulated Ultra-violet radiation. The degradation rate was found up to 99.19% within 150 Min. The influence of QDs as corrosion inhibition on zinc plate in three aerated electrolytes solutions namely NaCl, HCl and KOH was studied by Tafel polarization technique. The result showed that corrosion resistance succeeded due to CdS/MWCNTs QDs coating over Zn surface.
