Abstract:
Molecular dynamics simulation is made to study configuration and total energy of 0.5mol%, 2.1mol%, 3.8mol% VB transition metal ions (V5+, Nb5+, Ta5+)/TiO2 in rutile at 300K and 101325 Pa. As 2.1mol% Ti4+ is substituted by dopants, configuration remains well with less mean-square displacements (MSDs), distinct planes of atoms and higher stability. Nb5+ incorporates into TiO6 octahedra well and shows a large solubility in TiO2 compared with V5+ or Ta5+ due to comparable valence and ionic radius between Nb5+ and Ti4+.
