通过碳化物调理和化学去合金化，制备了具有精确可控结构特征和良好物理化学性能的新型3D纳米孔石墨烯、3D纳米孔无定形碳和3D纳米孔石墨烯/碳复合材料。这些新材料催生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的铂单原子催化剂，用于高密度锂离子电池负极的介孔石墨烯/二氧化钛复合材料，以及用于高倍率钠离子电池负极的纳米孔无定形碳。这些3D纳米多孔石墨烯和碳作为一类新的功能材料实现了高效的能量转换和存储。

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.
