Key Points

The aim is to assess the performance of a novel anti-corrosive coating derived from rice husk for protecting ASTM A36 steel in acidic environments.
Evaluated the corrosion performance of EP@MNS@APTES in 1 M HCl solution.
Characterized the coating using adsorption isotherm studies, focusing on the Langmuir model.
Measured inhibition efficiency and thermodynamic properties of the coating.
Achieved 98.71% inhibition efficiency at the optimum point.
Experimental data conformed excellently to the Langmuir isotherm model.
Coating adsorption was found to be spontaneous, thermodynamically favorable, and endothermic.

Implication

Evaluates anti-corrosive coating effectiveness in steel, indicating high efficiency and favorable thermodynamics.
