This study investigated the structure, intermolecular forces, electronic features, and durability of complexes formed between Eriochrome black T dye (EBT) and BC3 nanotube (BC3NT) in a solution using density functional theory modeling. The results showed that the adsorption mechanism of EBT on BC3NT is mainly controlled by donor-acceptor interactions between EBT and the boron atom of the tube via its O atom. This study also demonstrated the significant impact of EBT on the electrical features of BC3NT, making them suitable for the adsorption process.
Herein, we aim to investigate the structure, intermolecular forces, electronic features, and durability in a solution of complexes formed between Eriochrome black T dye (EBT) and BC3 nanotube (BC3NT) by density functional theory modeling. Possible applications for the removal of EBT were studied with the help of BC3NT. The energy of adsorption is about -36.76 kcal/mol for the interaction between EBT and a boron atom of the tube via its O atom. The electrical features of BC3NT are significantly affected by EBT, making them appropriate for the adsorption process. Also, donor-acceptor interaction mainly controlled the adsorption mechanism of EBT. This work, on the one hand, boosts the enhancement of low-cost and tolerable heteroatom carbon-based materials. On the other hand, it systematically investigates the mechanism of adsorption heteroatom carbonaceous structures for EBT.
