Abstract

 We have performed density functional theory investigations on the ADSORPTION properties of ammonia molecule on the undoped and N-doped TIO2 anatase nanoparticles. We have geometrically optimized the constructed undoped and N-doped nanoparticles in order to fully understand the ADSORPTION behaviors of ammonia molecule. For TIO2 anatase nanoparticles, the binding site is preferentially located on the fivefold coordinated titanium sites. However, we have mainly studied the interaction of NH3 molecule over the fivefold coordinated titanium sites including the bond lengths, bond angles, ADSORPTION energies, DENSITY OF STATES (DOSs) and molecular orbitals. The results indicated that the ADSORPTION of NH3 molecule on the N-doped nanoparticles is energetically more favorable than the ADSORPTION on the undoped one, suggesting the strong ADSORPTION of NH3 molecule on the N-doped nanoparticles. ADSORPTION on the N-doped nanoparticles leads to the more stable and favorable complexes. Our theoretical work represents that the N-doped nanoparticles have higher sensing capability than the pristine ones to remove the hazardous NH3 molecules from the environment.
