| 摘 要： | 过氧化物在裸玻碳电极表面还原过电位较高，反应速度较慢。而石墨烯修饰电极能催化还原有机过氧化物，降低过电位441mV。本文研究了石墨烯修饰电极催化还原过氧化氢、氢过氧化异丙基苯、氢过氧化叔丁基、过氧化丁酮等过氧化物的反应机理。石墨烯修饰电具有较高的稳定性和重现性，可用于这些物质的定量检测。

| Abstract: | This paper demonstrates that organic peroxides can be catalytically reduced at a graphene modified electrode. While on a bare glassy carbon electrode, none of the peroxides can be reduced within the potential range studied. When used in amperometric analysis, the modified electrode permits the detection of model organic peroxides such as t-butyl hydroperoxide, 2-butanone peroxide and cumene hydroperoxide by reduction mechanism at higher potentials without the interference from oxygen. The response is stable and has a wide dynamic range. |
