At present, a highly sensitive hydrogen peroxide (H2O2) sensor is fabricated by ferrocene based naphthaquinone derivatives as 2,3‐Diferrocenyl‐1,4‐naphthoquinone and 2‐bromo‐3‐ferrocenyl‐1,4‐naphthoquinone. These ferrocene based naphthaquinone derivatives are characterized by H‐NMR and C‐NMR. The electrochemical properties of these ferrocene based naphthaquinone are investigated by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS) on modified glassy carbon electrode (GCE). The modified electrode with ferrocene based naphthaquinone derivatives exhibits an improved voltammetric response to the H2O2 redox reaction. 2‐bromo‐3‐ferrocenyl‐1,4‐naphthoquinone show excellent non‐enzymatic sensing ability towards H2O2 response with a detection limitation of 2.7 μmol/L a wide detection range from 10 μM to 400 μM in H2O2 detection. The sensor also exhibits short response time (1 s) and good sensitivity of 71.4 μA mM−1 cm−2 and stability. Furthermore, the DPV method exhibited very high sensitivity (18999 μA mM−1 cm−2) and low detection limit (0.66 μM) compared to the CA method. Ferrocene based naphthaquinone derivative based sensors have a lower cost and high stability. Thus, this novel non‐enzyme sensor has potential application in H2O2 detection.

二茂铁基萘醌的合成及其在新型非酶过氧化氢中的应用

目前,高灵敏度的过氧化氢(H 2 O 2)传感器是由二茂铁基萘醌衍生物制成的,其衍生物为2,3-二茂铁基-1,4-萘醌和2-溴-3-三茂铁基-1,4-萘醌。这些二茂铁基萘醌衍生物的特征在于H-NMR和C-NMR。通过循环伏安法(CV),微分脉冲伏安法(DPV)和电化学阻抗谱(EIS)在改性玻璃碳电极(GCE)上研究了这些二茂铁基萘醌的电化学性质。具有二茂铁基萘醌衍生物的修饰电极对H 2 O 2表现出改进的伏安响应氧化还原反应。2-溴-3-三茂铁基-1,4-萘醌对H 2 O 2响应具有出色的非酶敏能力,检测极限为2.7μmol/ L,在H 2 O 2中的检测范围从10μM到400μM检测。该传感器还具有响应时间短(1 s)和71.4μAmM -1  cm -2的良好灵敏度以及稳定性。此外,与CA方法相比,DPV方法显示出非常高的灵敏度(18999μAmM -1  cm -2)和低检测限(0.66μM)。基于二茂铁的基于萘醌衍生物的传感器具有较低的成本和较高的稳定性。因此,这种新型的非酶传感器在H中具有潜在的应用2 O 2检测。
