Electrocatalytic Reaction

The bactericidal activity of an electrochemical system with a cobalt(II) phthalocyanine-modified Ti electrode was studied. In the presence of NaBO 3, strong bactericidal activity was observed against E. coli with electroreduction for 30 min. If an unmodified Ti electrode was used, no bactericidal activity was observed in the electrochemical system. By the ESR spin-trapping method using 5,5-dimethyl-1-pyrroline-N-oxide as the spin-trapping reagent, the radical species generated in the electrocatalytic reaction was found to be hydroxyl radical, which acts as the potent cytocidal species in the system.
