TiO2 commercial sample was feature using XDR technique to determine phase and crystallites average size. Bulk and (001) surface models were simulated for TiO2 material using DFT/B3LYP and its results were used for calculating energy surface, electronic levels, superficial atomic displacement and charge maps. Atoms of the first and second layers of the slab model showed electronic densities very well organized in the form of chains or wires.920-923porDFTTiO2rutileEnergia de superfície para nanossuperfícies de TiO2 na direção (001)Surface energy for (001) TiO2 nanosurfacesArtigo10.1590/S0100-40422012000500011S0100-40422012000500011WOS:000306136000011Acesso abertoS0100-40422012000500011.pdf
