研究了利用LB膜技术制备的蒙脱土-钌(Ⅱ)螯合物杂化膜(Clay-Ru)修饰电极对单磷酸鸟苷的光电催化氧化行为.实验结果表明:(1)蒙脱土-钌(II)螯合物的纳米单层杂化膜的平均厚度约为(3.4±0.5)nm;(2)紧密排列于ITO电极表面的非电活性蒙脱土的加入降低了电极的电化学活性,但有效提高了电极的稳定性;(3)具有供电子能力的单磷酸鸟苷(GMP)的加入,能大大提高ITO/Ru和ITO/Clay-Ru修饰电极的电子传递效率;(4)纳米单层蒙脱土-钌(II)螯合物杂化膜修饰电极的电子传递直接通过蒙脱土纳米单层进行.
The photoelectrocatalytic oxidation of guanosine monophosphate was studied by using Langmuir-Blodgett (LB) membrane-modified Clay-Ru modified electrode. The experimental results show that: (1) - (2) the addition of non-electroactive montmorillonite closely arranged on the surface of the ITO electrode reduces the electric charge of the electrode (3) The electron donating guanosine monophosphate (GMP) can greatly improve the electron transfer efficiency of ITO / Ru and ITO / Clay-Ru modified electrodes; ( 4) Nano monolayer montmorillonite - ruthenium (II) chelate hybrid membrane modified electrode electron transfer directly through the montmorillonite nano monolayer.
