KINETICS OF CATHODIC OXYGEN REDUCTION REACTION ON Q235 STEEL IN A SIMULATED CONCRETE PORE SOLUTION IN SEAWATER ENVIRONMENT
Q235钢在模拟海水环境混凝土孔隙液中阴极氧还原反应的动力学研究

Cyclic voltammetry and rotating disk electrode voltammetry were used to study the kinetics process of cathodic oxygen reduction reaction(ORR)on Q235 steel in an artificial solution simulated concrete pore liquor in seawater environment.The results show that the ORR in 0.02 mol/L Ca(OH)2 solution was a two-electron reaction companying with that O2 reduced to HO-2,which was controlled by a mixed process of charge transfer and mass transport,at the potentials of the beginning of ORR.Thereafter it was a four-el...
