We have prepared a multicomponent glass, in which photocatalytic Bi2O3Nb2O5 and Bi2O3SiO2 phases are crystallizable, and have examined the nanometric structure and photocatalytic activity in the resulting glassceramics (GCs). The GCs crystallized the Bi3NbO7 nanophase followed by the Bi5Nb3O15 nanophase as increasing the heat-treatment temperature, and eventually, the nano-sized Bi5Nb3O15Bi4Si3O12 co-crystallized GC sample was obtained. Although photocatalytic activity was confirmed in the singly Bi3NbO7-/Bi5Nb3O15- crystallized samples by means of the degradation test of rhodamine B dye, a higher activity was found in the cocrystallized sample. The high photocatalytic activity was considered in accordance with a nanometric structural observation.
