We developed a submerged radical reactions method for the fabrication of metal nano oxides for photo functional applications. Theradical reactions were mainly generated by light illumination, ultrasound, and reactive oxygen species (ROS). In this year's work, we mainly focused on the nanostructure fabrication on copper and copper alloys surface by using the ROS of H2O2-HClO mixture solutions.The XRD and SEM results show that a homogeneous nanostructure surface can be obtained under both UV and visible light illumination when the volume ratio of HClO to H2O2 is 2:1.The Raman spectroscopy analysis proved that CuO, Cu2O and Cu2Cl(OH)3 are formed on the metal surface.The cyclic voltammetry measurement shows that the sample with visible illumination has the highest specific capacitance.

我们发展了一种浸没式自由基反应方法来制备具有光功能应用的金属纳米氧化物。治疗反应主要由光照、超声和活性氧（ROS）产生。本论文的主要工作是利用H2 O2-HClO混合溶液中的活性氧在铜及铜合金表面制备纳米结构，XRD和SEM结果表明，当HClO与H2 O2的体积比为2：1时，在紫外光和可见光照射下均能获得均匀的纳米结构表面。1.拉曼光谱分析表明，循环伏安法测试表明，可见光照射下样品的比电容最高。
