英文摘要： Based on conducting polymers(CPs)/nanoporous metal composite electrode, novel voltammetric sensors with high sensitivity and high selectivity, which could be suitable for the extreme environments，will be designed and fabricated via dealloying method and electrochemical polymerization technique. By investigating the electrochemical behaviors and characterizing the microstructrues of the voltalmmetric sensors, the effect rules of the nanoporous structures and the inner electronic fields on the performance of the voltammetric sensors will be revealed. Meanwhile, the structure and stability of interface between CPs and nanoporous metal will be investigated deeply. At the same time, the underlying relationships between the essential features of nanoporous metal as well as the compositions of the ion-selective nanofilms and the properties of the voltammetric sensors will be demonstrated. Based on above study, the sensing mechanism of voltammetric sensors constructing by CPs/nanoporous metal composite electrodes will be founded and the voltammetric sensors and their sensor arrays will be intergrated and optimized in the end, which can probably explore an approach for fabricating new generation voltammetric sensors. And our work will therefore provide prospective technique support for online monitoring underground water
