摘要碘化亚铜具有良好的光学性质和电学性质，而且价格低廉，广泛应用于催化和电 化学领域。石墨烯掺氮可以增强金属粒子与石墨烯的相互作用，提高材料各方面性能。 近年来，不同组合的有机/无机纳米复合材料的设计和制造吸引了学术和工业的显著 关注。在这些复合材料中很多努力都集中在聚苯胺和无机纳米晶体的组合，以产生新 的功能材料。83311

在实验中我们先用水热法合成掺氮石墨烯，之后又在碘化亚铜和聚苯胺合成的过 程中加入掺氮石墨烯，从而成功制备了 CuI/掺氮石墨烯/PANI 纳米复合材料。并使用 扫描电镜（SEM）、红外光谱（FTIR）测试、X-射线衍射分析（XRD）对其进行表 征，用光催化性能测试、电化学性能测试测定了其光催化和电化学性能以确定最佳配 比。实验结果显示，三种物质已经成功复合，并且由于 CuI、掺氮石墨烯和聚苯胺之 间的协同效应，提高了材料的性能，使其光催化和电化学性能的应用潜力更加突出。

AbstractCuI has good optical and electrical properties, and the price is low, widely used in catalytic and optical fields。 Nitrogen doped graphene can enhance the interaction between metal particles and graphene, and improve the properties of materials。 In recent years, different combinations of organic/inorganic nanocomposites have attracted significant attention in the design and manufacture of science and industry。 In these composite materials, many efforts have been focused on the combination of polyaniline and inorganic nanocrystals to produce new functional materials。

In the experiment, we first use the hydrothermal method to synthesize nitrogen doped graphene, and later nitrogen doped grapheme is added in the synthesis process of CuI and polyaniline, thus CuI/nitrogen doped graphene /PANI nanocomposites were successfully prepared。 And use scanning electron microscopy(SEM), infrared spectroscopy(FTIR) test, X-ray diffraction analysis(XRD) to characterize it, the photocatalytic and electrochemical properties were determined by photocatalytic performance test and electrochemical performance test for the best ratio in the other hand。 Experimental results show that, three substances have been successfully combined, and due to the synergistic effect between CuI, nitrogen doped graphene and polyaniline, the performance of the material is improved, and the photocatalytic and electrochemical properties are more prominent。
