Abstract:
This study investigated the potential of pristine and Al-doped BN nanoclusters (B۱۲N۱۲, AlB۱۱N۱۲) as adsorbents and sensing materials for the removal and detection of Chloral hydrate (CH) using density functional theory computations. The calculated values of adsorption energies, ΔGad, ΔHad, and Kth revealed that CH interaction with B۱۲N۱۲ is experimentally impossible, endothermic, and non-spontaneous. However, the CH adsorption on the AlB۱۱N۱۲ is exothermic, spontaneous, and experimentally feasible. The influence of solvent was also considered, and the results indicated that the presence of water does not significantly affect the interactions. Furthermore, the Natural Bond Orbital (NBO) computations showed that no chemical bond has formed between the adsorbate and adsorbent, indicating that the interactions between CH and both nanoclusters are due to physisorption. Moreover, frontier molecular orbital calculations indicated that while the bandgap of B۱۲N۱۲ remains largely unchanged during the CH adsorption process, the bandgap of AlB۱۱N۱۲ increases by ۱۳۲.۶۹۳% from ۴.۲۷۰ eV to ۹.۹۳۶ eV. In conclusion, the theoretical findings suggest that the Al-doped nanocluster, AlB۱۱N۱۲, has the potential to be an excellent adsorbent and sensor for the removal and detection of Chloral hydrate. This study provides valuable insights into the use of nanoclusters in environmental and analytical applications, highlighting the potential for developing efficient materials for CH removal and detection. Further experimental validation of these theoretical findings could pave the way for the practical application of Al-doped boron nitride nanoclusters in addressing environmental and analytical challenges associated with Chloral hydrate.
