Nitrogen and sulfur codoped carbon dots (SB-CDs) were developed from sugar cane bagasse, an agro-industrial waste, evaluated as eco-friendly corrosion inhibitor for Q235B steel in HCl solution. The surface coverage of the adsorbed SB-CDs is strongly influenced by immersion time (6 72 h, both static dynamic conditions) concentration (20-200 mg/L). Maximum uniform achieved with 150 mg/L SB-CDs. At this concentration, demonstrated a high inhibition efficiency 96% after 6 h immersion, maintaining effectiveness at 94 92% under conditions, respectively, immersion. Electrochemical studies showed that polarization resistance (Rp) increased, current density (Icorr) decreased presence compared to uninhibited specimens, confirming SB-CDs' adsorption on metal surfaces. Additionally, analysis using scanning electron microscopy atomic force confirmed improved morphology fewer features, supporting formation protective film. Energy-dispersive X-ray photoelectron spectroscopy analyses further confirm layer SB-CDs, attributed interaction nitrogen-, oxygen-, sulfur-containing functional groups surface. Therefore, homogeneously entirely blocks iron chloride/oxide/hydroxide intermediates, ensuring corrosive environments.
