摘要
石墨烯独特的单原子层结构使其具有许多让人振奋的物理化学性质,例如高机械强度、高理论比表面积、高速载流子迁移速率以及良好的导热性质,这些优异的性质使得石墨烯在电子、材料、生物医学等领域展现出广阔的应用前景~([1,2]),也因此成为当前国际上关于能量存储与转换的热点研究材料~([3,4])。由单层的石墨烯薄片所构成的三维宏观组件中,石墨烯三维泡沫结构已经引起极大关注,它既继承了单层石墨烯的优良性能并且表现出独特的结构和功能,是实现单层石墨烯宏观应用的重要策略~([5])。本文通过设计构筑一种方便、无毒、高效的方法制备氧化锌纳米棒阵列修饰的自支撑石墨烯泡沫~([6]),可以使石墨烯表现出独特的网络结构、高比表面积以及出色的电子和机械性能,其导电孔状结构,可提高光捕获效率和电子传输速率;此外,在石墨烯表面的氧化锌纳米棒作为活性介质能够极大的提高光电流的生成和光催化效率。这使其在能源存储应用、复合材料、催化、柔性电子产品、环境整治和检测等方面表现出巨大的应用潜力,而且这样的结构也可能为宏观材料的化学功能化和超分子工程学开辟新的途径。
Fabrication of macroscopic structures with nanomaterials, while keeping the original properties of nano-building blocks, is of great significance to promote the practical applications. In the field of material science, graphene has received much attention because of its unique structure, excellent physical and chemical properties, such as mechanical strength, big specific surface area, biocompatibility and chemical stability. Interconnected 3D graphene foams have gained tremendous attention recently due to their unique structure and superior physical properties. The reasonable design and preparation of composite foams can help promote the sunlight utilization and improve the conversion efficiency. Such composite graphene foam is a good candidate as photocatalyst for the photodegradation of organic pollutants, which cause severe environmental and ecological problems every year.
