| Outline of Annual Research Achievements |
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.
