摘要
The effect of cationic surfactant, dodecyltrimethyl ammonium bromide (DTAB), on oxygen reduction reaction was studied by rotating vitreous carbon disk electrode. The results showed that the catalytic activity of vitreous carbon electrode on oxygen reduction reaction could be improved significantly by DTAB. From the analyses on the relation between the current of oxygen reduction and rotating speed of the electrode and the Tafel relation between kinetic current and potential, it was found that DTAB promoted the transfer coefficient of charge transfer step for oxygen reduction reaction on vitreous carbon electrode, thus improved the kinetics of oxygen reduction reaction.
