چکیده

Adsorption of NO₂ molecule on pristine and N-doped TiO₂ anatase nanoparticles have been studied using the density functional theory (DFT) technique. The structural properties (such as bond lengths and bond angles) and the electronic properties (such as density of states, band structures and atomic partial charges) have been computed for considered nanoparticles. The results show that, the adsorption of NO₂ molecule on N-doped nanoparticles is more energetically favorable than the adsorption of NO₂ molecule on the pure TiO₂ nanoparticles. However, on the base of the obtained results, the N-doped TiO₂ nanoparticles can be used in NO₂ sensing and removing applications.
