Abstract
ABSTRACT The interactions of hydrazine (HZ) with fullerene C20, C40, and C60 adsorbents are interpreted in the current study using density functional theory (DFT). In order to demonstrate the interaction behaviour, we have studied the adsorption energies, dipole moments, HOMO–LUMO orbital analyses, global indices, thermodynamic parameters, and UV-vis spectra. We found that HZ adsorp with a maximum adsorption energy of – 14.03 KJ/mol on C20 surfaces, i.e. physisorption interaction, and the interaction type is exothermic. The MEP map analysis displayed that charges had been transferred between the adsorbent and adsorbate after the interaction. To describe the details of interaction behaviour, we examined the densities of states (DOS). Moreover, the QTAIM analysis found that substantially all complexes had a weak electrostatic interaction. Our study displayed that fullerene C20 has a better sensing ability towards HZ than fullerene C40 and C60 which will help to keep people safe from the harmful effects of HZ and be used in cancer research, as rocket fuel in spacecraft, as an emulsifier, a catalyst, a blowing agent, and as a precursor in various pharmaceutical products.
