Novel hollow graphene flowers (HGFs) are synthesized by a Cu‐assisted chemical vapor deposition. Multilayer graphene films and vertical‐oriented graphene nanosheets are grown on hollow silica spheres successively by controlling the CH₄/H₂ flow and growth time. After graphene growth, HSS templates are removed to achieve HGFs. The π‐conjugated systems and unique morphology of HGFs lead to apparent adsorption ability for dyes and phenol molecules. This work provides a facile way to produce unique hollow structure graphene with massive edges for different applications in the future.

铜辅助化学气相沉积法合成新型空心石墨烯花

新型中空石墨烯花（HGF）是通过Cu辅助化学气相沉积法合成的。通过控制CH ₄ / H _2的流量和生长时间，可以在空心二氧化硅球上连续生长多层石墨烯薄膜和垂直取向的石墨烯纳米片。石墨烯生长后，将HSS模板移除以获得HGF。HGF的π共轭体系和独特的形态导致对染料和酚分子的明显吸附能力。这项工作为将来生产具有大量边缘的独特空心结构石墨烯提供了一种简便的方法。
