Abstract
A series of B doped TiO2 samples were synthesized by a simple sol-gel method. The existing states, doping behavior and the influence on the phase transition for the introduced boron ions are investigated and studied in details. It is noted that the B3+ ions are mainly incorporated into TiO2 lattice in interstitial mode. The excessive B3+ ions form surface B2O3 species on the surface of TiO2 with the increase amount of boron ions. Furthermore, the introduction of B3+ ions in interstitial mode inhibits the formation of rutile and delay the phase transition. These results afford better realization about the doping mechanism of B doped TiO2.
