Carbon nanomaterials, mainly carbon nanotubes (CNTs) and graphene, have received much attention in the past two decades. With the maturity of preparation technology and performance studies, they have been gradually applied in the industries of lithium-ion batteries (as conductive agents) and supercapacitors (as the main electrode materials). The large-scale production (up to thousands of tons per year) of CNTs has been realized, and the production cost has been greatly reduced. The production of graphene also exceeds one hundred tons per year, requiring the same improvement in performance/cost ratio. As one of the cheapest hydrocarbons, methane serves as a feedstock of both CNTs and graphene. The catalytic methane technology via the chemical vapor deposition method is advantageous for the controlled synthesis and mass production of carbon materials with high yield, high quality and at low cost, which are necessary requirements for any potential yet competitive commercial applications. Firstly, the methane deposition of CNTs is discussed, with a brief introduction on the preparation of CNTs, then the growth mechanism of CNTs, thermodynamics of methane decomposition in CNT synthesis, catalysts to decompose methane for CNT growth, and the synthesis of CNTs with different structures from methane. Secondly, the methane deposition of graphene is discussed, with a brief introduction on the preparation of graphene, then the growth kinetics of graphene, the quality estimation of graphene, and the synthesis of graphene with different structures from methane. Finally, the reactor technology for the enhanced production of CNTs and graphene is introduced, including the large-scale production of powder-like CNTs and graphene, ultralong CNTs, and graphene films, respectively. The review is useful for understanding the scientific and engineering challenges in this field and for the large-scale production of these important carbon nanomaterials from methane in the future.

碳纳米管和石墨烯的催化甲烷技术
在过去的二十年中，碳纳米材料（主要是碳纳米管（CNT）和石墨烯）受到了广泛关注。随着制备技术和性能研究的成熟，它们已逐渐应用于锂离子电池（作为导电剂）和超级电容器（作为主要电极材料）的行业。已经实现了CNT的大规模生产（每年多达数千吨），并且大大降低了生产成本。石墨烯的产量每年也超过一百吨，需要在性能/成本比上进行同样的改进。甲烷是最便宜的碳氢化合物之一，是碳纳米管和石墨烯的原料。催化甲烷技术通过化学气相沉积法有利于以高收率，高质量和低成本进行碳材料的受控合成和批量生产，这对于任何潜在的但有竞争力的商业应用都是必不可少的要求。首先讨论了碳纳米管的甲烷沉积，简要介绍了碳纳米管的制备方法，然后介绍了碳纳米管的生长机理，碳纳米管合成中甲烷分解的热力学，用于甲烷生长的分解甲烷的催化剂以及不同碳纳米管的合成。甲烷的结构。其次，讨论了石墨烯的甲烷沉积，并简要介绍了石墨烯的制备，石墨烯的生长动力学，石墨烯的质量估算以及与甲烷结构不同的石墨烯的合成。最后，介绍了用于增强碳纳米管和石墨烯生产的反应器技术，包括分别大规模生产粉末状碳纳米管和石墨烯，超长碳纳米管和石墨烯薄膜。这篇综述对于理解该领域的科学和工程挑战以及将来从甲烷大规模生产这些重要的碳纳米材料很有用。
