| Abstract Scope |
Preparation of two-dimensional materials (2D) has predominantly been through selective etching of layered solids. Herein, we convert – near ambient conditions – a dozen of commercial water-insoluble Ti-containing precursors including TiC, TiN, and TiB2 into one-dimensional (1D) nanofilaments that self-align in 2D flakes. Simply, the precursor is treated in tetramethylammonium hydroxide solution at 50-80°C for a few days. Using a battery of techniques, we conclude that the resulting entities are C-containing anatase-based 1D nanofilaments that are ≈ 6 x 10 Å2 in cross-section and few microns long. The filaments/flakes showed enhanced electrochemical performance as cathodes in both Li-ion and Li-S batteries. They also found to reduce the viability of cancer cells thus showing potential in biomedical applications. The developed synthesis protocol of 1D and 2D materials in bulk-scale at near ambient conditions is paradigm shifting and will undoubtedly open new and exciting avenues of research and applications. |
