We investigated oxidation and reduction responses of hydrogen peroxide using a carbon electrode with platinum particles deposited by cathodic reduction of cis-diamminedichloroplatinum（II）（cisplatin）. Platinum deposition led to a marked increase of oxidation and reduction currents for hydrogen peroxide compared to currents observed using the carbon electrode without platinum. The reduction response is particularly useful for determination of cisplatin because the electrochemical reaction forms no bubbles.
