Abstract
The redox catalysis of oxygen reduction was performed on a platinum ro tating disk electrode. The Fe(III)/Fe(II)/H2SO4 system at different pH 's was used as a MEDIATOR. The catalytic effect of mediator was direct ly related to the solvation sphere of Fe(III) and Fe(II). Only the red ox couple FeHSO42+/FeHSO4+ (pH<0) showed a catalytic effect on oxygen reduction.
