Abstract Carbon hybrids (CHs) with controllable synthesis and hierarchical structures have been considered as promising materials to satisfy the explosive energy consuming. Here, a novel strategy is demonstrated to design hierarchical CHs by reductive-catalytic chemical vapor deposition (RCCVD). The graphene oxide sheets self-assemble into microfiber skeleton during wet-spinning, combining with in situ growth of carbon hybrid nanofibers by the catalytic species from RCCVD. The derivatives from RCCVD exhibit diverse microstructures of nanocaps, nanofibers and nanorods under different synthesis temperatures. Ammonia (NH3), hydrogen cyanide (HCN) and cyanic acid (HCNO) are released efficiently as the reductant by the synergy of ion-contained graphene oxide and melamine. The microassemblies display satisfactory performance as LIB anodes ascribed to the well-designed micro-nano hierarchical structures. This work provides a feasible strategy to synthesize functional carbon-based hierarchical assemblies.

通过还原催化化学气相沉积合理设计分级碳杂化微组件

摘要 具有可控合成和分级结构的碳杂化物（CHs）被认为是满足爆炸性能量消耗的有前途的材料。在这里，展示了一种通过还原催化化学气相沉积 (RCCVD) 设计分层 CH 的新策略。氧化石墨烯片在湿纺过程中自组装成微纤维骨架，结合来自 RCCVD 的催化物种的碳杂化纳米纤维的原位生长。来自 RCCVD 的衍生物在不同的合成温度下表现出不同的纳米帽、纳米纤维和纳米棒的微观结构。通过含有离子的氧化石墨烯和三聚氰胺的协同作用，氨（NH3）、氰化氢（HCN）和氰酸（HCNO）作为还原剂被有效释放。由于精心设计的微纳米分层结构，微组件作为 LIB 阳极表现出令人满意的性能。这项工作为合成功能性碳基分层组件提供了一种可行的策略。
