Abstract
In this research, the interaction of the acrolein (Acr) molecule with the pristine and Ga‒doped boron phosphide nanotube (BPNTs) was investigated using the density functional theory (DFT). The electrical, quantum, thermodynamic properties, natural bond orbital (NBO), reduced density gradient (RDG), atom in molecule (AIM), and molecular electrostatic potential (MEP) for all studied models were calculated and analyzed. The results revealed that the thermodynamic parameters (∆H and ∆G) values for all studied models were negative and favorable in thermodynamic point of view. By doping the Ga atom and adsorbing Acr molecule, the HOMO, LUMO, gap energy, conductivity, and optical properties of the nanotube altered slightly from the original values. Whereas, the global hardness and chemical potential of the Ga-doped increased slightly from pristine state and the activity of system decreased slightly from the original state. In addition, the AIM parameters and RDG results showed that the covalent bonding interaction between Acr and BPNTs was so strong.
