My research interests include synthesis, characterization, modifications, properties, and assemblies of novel graphitic carbon nanomaterials (Graphene and its derivatives, carbon nanotubes with aligned arrays and doped arrays, heteroatom-doped graphene/CNTs, carbon onions, carbon nanocoils, carbon spheres, etc.), 2D analogous inorganic layered materials (MoS2, WS2, BN, MXenes, g-C₃N₄, etc.), and 3D graphene-metal oxide/graphene-CNTs hybrids, etc. for use in multi-functional applications, especially for energy (energy storage/conversion), sensing, and EMI shielding.
