Graphene is a single sheet of carbon atoms with outstanding electrical and physical properties and is being exploited for applications in electronics, sensors, photovoltaics, and energy storage. A novel 3D architecture called a pillared graphene nanostructure (PGN) is a combination of two allotropes of carbon, including graphene and carbon nanotubes. A one-step chemical vapor deposition process for large-area PGN fabrication via a combination of surface catalysis and in situ vapor-liquid-solid mechanisms is described. A process by which PGN layers can be transferred onto arbitrary substrates while keeping the 3D architecture intact is also described. Single and multilayer stacked PGNs are envisioned for future ultralarge and tunable surface-area applications in hydrogen storage and supercapacitors.
石墨烯是一种由碳原子组成的单层结构，具有出色的电学和物理性能，目前正被应用于电子、传感器、光伏和储能等领域。一种名为支柱石墨烯纳米结构（PGN）的新型 3D 架构是石墨烯和碳纳米管两种碳同素异形体的组合。本文描述了一种通过表面催化和原位气-液-固机制相结合的一步法化学气相沉积工艺，用于大面积 PGN 的制备。还描述了一种可以将 PGN 层转移到任意衬底上而保持 3D 结构完整的方法。单层和多层堆叠的 PGN 有望在未来的氢气存储和超级电容器等超大表面积可调应用中得到应用。
