Anticorrosion behaviour of green synthesized fluorescent carbon nanoparticles on Q235 steel

Abstract

In this research work, green fluorescent carbon nanoparticles (CNPs) were synthesized from Spider dragline silks (Crossopriza lyoni) by simple pyrolysis techniques at temperature of 400 ⁰C without using of any toxic chemicals. The synthesized CNPs were comprehensively characterized by using Field emission scanning electron microscopy (FESEM) with Energy Dispersive X-Ray (EDX) analysis, X-Ray diffraction (XRD), UV-Visible, Fourier transform infrared (FTIR), Raman and fluorescence spectroscopy. The anticorrosion behaviour of green synthesized fluorescent CNPs on Q235 steel in 1 M HCl solution was examined through electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization curves (PDP) analysis. The obtained electrochemical results showed that the green synthesized CNPs could effectively inhibit the corrosion of Q235 steel in 1 M HCl solution. Additionally, the corrosion resistance behaviour was characterized by XRD and Scanning electron microscopy (SEM) analysis.
