采用二巯基化合物将CdS-FePt纳米二聚体固定在金电极上，制备了一种不含氧化还原介体的新型H2 O2传感器。在光照条件下，电子从金电极到CdS量子点的转移是通过电子隧穿过程进行的。由于FePt纳米粒子与CdS的结合具有催化性质，光生电子可以进一步传递给H2 O2，产生催化光电流。本文描述了传感器的制备过程，并研究了CdS-FePt二聚体修饰金电极的特性。结果表明，在检测范围内，光电流幅值与H2 O2浓度呈线性关系，光电化学信号的性质受外加电位的影响。
By fixing CdS-FePt nanodimers on gold electrodes with dithiol compounds, a new H2O2sensor without any redox mediator was developed. Under illumination, electron transfer from gold electrode to CdS-QDs will occur by electron tunneling process. Because of the catalytic properties of FePt-nanoparticles associated with the CdS, photoinduced electrons can be further transferred to H2O2resulting in a catalytic photocurrent In this paper, the fabrication process of sensor was described and the characteristics of the CdS-FePt dimers modified gold electrodes were investigated. The results showed that the amplitude of photocurrent changed with the H2O2concentration linearly in detection range and the properties of photoelectrochemical signals were influenced by the applied potential.
