While there have been tremendous studies about graphene and its applications in the past decade, so far the proposed huge potential of this material has not been materialized. One of the prerequisites to overcome these challenges is maintaining the nature and intrinsic properties of individual graphene sheets while in the state of bulk material. Thus, in this Perspective contribution, the fabrication/synthesis of the monolithic polymeric and three-dimensional (3D) cross-linked bulk materials (3DGraphene) with (doped) 2D graphene sheets as the building block will first be briefly summarized. Then, the second part will cover the redox catalytic application of these bulk materials including doped 3DGraphene, the graphene-like material polymeric CN and their hybrid materials. These will include mainly oxygen reduction reactions (ORR), hydrogen evolution reactions (HER), and CO reduction for their latest development. Finally, challenges and outlook related to the design of 3D cross-linked graphene based materials and their catalytic applications will be briefly discussed.
在过去十年里，虽然已经有大量关于石墨烯及其应用的研究，但迄今为止，这种材料所展现出的巨大潜力尚未实现。克服这些挑战的前提之一是在块状材料状态下保持单个石墨烯片层的性质和固有特性。因此，在这篇展望文章中，将首先简要总结以（掺杂的）二维石墨烯片为构建单元的整体聚合物和三维（3D）交联块状材料（3D石墨烯）的制备/合成方法。然后，第二部分将涵盖这些块状材料的氧化还原催化应用，包括掺杂的3D石墨烯、类石墨烯材料聚合物CN及其混合材料。这将主要包括氧还原反应（ORR）、析氢反应（HER）以及它们在CO还原方面的最新进展。最后，将简要讨论与三维交联石墨烯基材料的设计及其催化应用相关的挑战和前景。
