三维（3D）分级微/纳米定向阵列构建从纳米尺寸的积木代表了一组重要的材料，并已收到了巨大的关注，为一系列的应用，因为它们可以提供纳米尺寸的积木和微米或亚微米尺寸的有序阵列的优点。本文采用氨基酸辅助仿生水热法合成了银纳米粒子修饰的三维花状超亲水CuO微/纳米结构。实验表明，该产品在润湿性（没有高自由能化合物的帮助，在没有紫外线照射的情况下）和增强的光催化活性方面表现出优异的阳光自清洁性能，这预示着该材料作为自清洁光伏涂料的光明前景。也是绿色化学与功能材料有机结合的典范。
Three-dimensionally (3D) hierarchical micro/nano oriented arrays constructed from nanometer-sized building blocks represent an important group of materials and have received enormous attention for a series of applications because they can offer both the advantages of nanosized building blocks and micro- or submicrometer-sized ordered arrays. In this work, 3D flower-like superhydrophilic CuO micro/nanostructures decorated by Ag nanoparticles were synthesized via an amino acid-assisted biomimetic hydrothermal method. Experiments reveal that the product demonstrates excellent sunlight self-cleaning performance in terms of wettability (without the help of high-free-energy compounds and in the absence of UV irradiation) and enhanced photocatalytic activities, which portends a bright future for this material as self-cleaning photovoltaic coatings. It is also a good example for the organic combination of green chemistry and functional materials.
