Through carbide mediation and chemical dealloying, new 3D nanoporous graphene, 3D nanoporous amorphous carbon, and 3D nanoporous graphene/carbon composite materials with precisely controlled structural features and desirable physicochemical properties have been developed. These new materials lead to the creation of advanced electrocatalysts and electrodes, such as mesoporous N-doped graphene for the oxygen reduction reaction, nanoporous graphene anchored Pt single-atom catalyst for electrochemical hydrogen production, mesoporous graphene/TiO2 composite for dense Li-ion battery anode, and nanoporous amorphous carbon for high-rate Na-ion battery anode. These 3D nanoporous graphene and carbon enable high-efficiency energy conversion and storage as a new class of functional materials.

通过碳化物介质和化学合金化，开发出结构特征可控、理化性能优良的新型三维纳米多孔石墨烯、三维纳米多孔非晶碳和三维纳米多孔石墨烯/碳复合材料。这些新材料带来了先进的电催化剂和电极，如用于氧还原反应的介孔n掺杂石墨烯，用于电化学制氢的纳米孔石墨烯锚定Pt单原子催化剂，用于致密锂离子电池负极的介孔石墨烯/TiO2复合材料，以及用于高倍率钠离子电池负极的纳米孔非晶碳。这些3D纳米多孔石墨烯和碳作为一种新型功能材料，能够实现高效的能量转换和存储。
