摘要本文采用循环伏安法在ITO 电极上制备基于 laponite的微纳级普鲁士蓝类化合物,采用了扫描电子显微镜、电化学方法以及傅里叶红外光谱等技术对合成的普鲁士蓝类似物的形貌特征以及性质进行了研究。结果表明,以 Laponite 作为阳离子交换剂可以得到稳定的普鲁士蓝复合物,且该修饰电极对卡托普利具有良好的电催化氧化作用。在卡托普利存在下,Fe(Ⅱ)/Fe(Ⅲ)的阳极峰电流增加,阴极峰电流减小,而Co(Ⅱ)/Co(Ⅲ)的峰值电流几乎保持不变。这表明,卡托普利在修饰电极的表面通过表面介导的电子传递而被氧化。 26727 毕业论文关键词 普鲁士蓝 Laponite 卡托普利 电催化氧化
Title Synthesis, characterization and bioelectrocatalytic behavior of prussian blue/laponite micro-nano materials
Abstract
In this paper, prussian blue/laponite micro-nano material was synthesized by
cyclic voltammetry on ITO electrodes. The modified electrode was characterized
by scanning electron microscope, transmission electron microscopy,
electrochemical, IR, and other technology. The results showed that using laponite
as cation exchangers, we can synthesize stabilized prussian blue compounds. The
modified electrode showed good electro-catalytic oxidation to captopril. In the
presence of captopril, Fe (Ⅱ) / Fe (Ⅲ) anodic peak current increases, and cathodic
peak current is reduced, while Co (Ⅱ) / Co (Ⅲ) peak current is almost unchanged.
This suggests that captopril was oxidized by surface-mediated electron transfer
on the modified electrode surface.
