New porous titanium-niobium oxide for photocatalytic degradation of bromocresol green dye in aqueous solution

The photocatalytic activity of different porous titanium-niobium oxides was evaluated toward degradation of bromocresol green (BG) under UV light. A better catalytic activity was observed for all samples at lower pH. Catalysts have a stronger ability for degradation of BG in acid media than in alkaline media.
