Sažetak
This work examines the effect of Pulicaria odora leaf extract effect as a green inhibitor on SS308 steel corrosion in a 1 mol L–1 hydrochloric acid solution. The electrochemical results reveal that inhibitory efficiency increases with the concentration of Pulicaria odora leaf extract, reaching a maximum inhibition rate of 94.6 % at 500 ppm. Potentiodynamic polarization curves suggest that the plant extract acts as an anodic-type inhibitor. The polarization and electrochemical impedance findings are in good agreement. Adsorption of the inhibitor on the steel surface is spontaneous and follows the Langmuir isotherm. Furthermore, a copper-based catalyst synthesized using Pulicaria odora extract produced a good yield, and this catalyst showed effective photodegradation of methylene blue. The CuO nanoparticles (NPs) synthesized from Pulicaria odora extract showed significant antimicrobial activity against the tested bacterial strains.
