Nanocarbon Materials

Carbon nanomaterials are nano-scale structural systems composed of carbon elements. Carbon nanomaterials have become the core research field of material science due to their unique physical and chemical properties and multi-dimensional structural characteristics. According to the dimension and bonding form, they mainly cover the following categories. Fullerenes are closed-cage molecules of sp²-hybridized carbon atoms, exemplified by C₆₀. Their high symmetry and delocalized π-electrons donate excellent electron acceptor characteristics. They have potential in optoelectronic devices and supramolecular assembly, however, they face challenges in functionalization and scalable synthesis. Nanocarbon unit structures refer to fundamental nanoscale building blocks (e.g., nanorings). The size effect and edge chemistry (e.g., functional group modification) can regulate photoluminescence, catalysis, and other properties, enabling atomic-level design of nanodevices. Carbon nanotubes (CNTs) are one-dimensional tubular structures formed by rolled graphene sheets, which can be divided into single-walled and multi-walled types. They exhibit axial strength, conductivity, and thermal conductivity. However, their poor dispersion necessitates dispersants to achieve homogeneity, which improve the interfacial compatibility of CNTs via π-π interactions or covalent modification. Graphene is a two-dimensional honeycomb lattice of sp² carbon, which has ultrahigh carrier mobility and mechanical strength. Graphene oxide is prepared by oxidative exfoliation, containing hydroxyl and epoxy groups. It has both solution processability and chemical modifiability at the cost of reduced conductivity, which needs to be partially restored via reduction. MXenes are derived from MAX phase etching (general formula Mn+1XnTx, M: transition metal, X: C/N/B, T: surface groups), exhibiting layered structures, high conductivity, and hydrophilicity for energy storage and electromagnetic shielding, however, the problem of interlayer restacking needs to be solved urgently. Carbon nanofibers (CNFs) are fabricated via electrospinning or CVD, combining high surface area and flexibility for electrodes and filtration. Nanodiamonds (NDs) are synthesized by detonation, and the sp³ hybrid structure endows them with extreme hardness and biocompatibility, whose application can be expanded in bioimaging and quantum sensing by surface functionalization.
