چکیده
Electronic properties of carbon nanotubes (CNTs) is enhanced with the help metal oxides which in turn paves way toward functionality CNTs for many applications based on their electronic properties. Accordingly, density functional theory at B3LYP/3-21g** utilized to model decoration and TiO2. 7 molecules TiO2 are interacted CNT surface as adsorb state complex. As a result this decoration, change Mulliken atomic charges atom recorded, changing both total dipole moment HOMO/LUMO bandgap energy. The molecular electrostatic potential localized left side then up down complex state, enhances probability forming hydrogen bonding surrounding. physical parameters promotes decorated applications. For verification, prepared homemade CVD XRD, TEM, TGA confirmed that located surface. Finally, FTIR spectrum indicated studied suitable investigated system regarding accuracy computational time.
