利用电化学还原氧化石墨烯(GO)的方法将还原石墨烯(erGO)沉积在电极表面上,然后电沉积氧化锌纳米棒(ZnO)构成erGO/ZnO复合纳米材料修饰玻碳电极(GCE),最后通过电聚合中性红(NR)电子介体包埋法将辣根过氧化物酶(HRP)固定在GCE/erGO/ZnO表面制得GCE/erGO/ZnO/HRP-PNR(聚中性红)。用SEM和能谱对复合纳米材料进行了表征,通过电化学阻抗法和循环伏安法对修饰电极进行了探究,通过循环伏安法和计时电流法研究了GCE/erGO/ZnO/HRP-PNR对有机过氧化物的催化性能,结果该修饰电极对过氧化氢叔丁基(BHP)和过氧化氢异丙苯(CHP)都具有良好的检测性能。
Electrodeposition of zinc oxide nanorods (ZnO) to form erGO / ZnO nanocomposites modified glassy carbon electrode (GCE) by depositing reduced graphene (erGO) on the electrode surface by electrochemical reduction of graphene oxide (GO) Finally, GCE / erGO / ZnO / HRP-PNR was immobilized on GCE / erGO / ZnO immobilized horseradish peroxidase (HRP) by electropolymerization of neutral red ). The composite nanomaterials were characterized by SEM and EDS. The modified electrodes were investigated by electrochemical impedance spectroscopy and cyclic voltammetry. The cyclic voltammetry and chronoamperometry were used to investigate the effect of GCE / erGO / ZnO / HRP-PNR The catalytic performance of the organic peroxide, as a result of the modified electrode of t-butyl hydroperoxide (BHP) and cumene hydroperoxide (CHP) have good detection performance.
