Abstract

Abstract: Boron/fluoride co-doped nano TiO₂ colorless and transparent hydrosol was synthesized by a novel complexation-controlled hydrolysis method at room temperature by using TiCl₄, oxalic acid, NH₃·H₂O, ammonium fluoride, and boric acid etc as raw materials. The sample with the acid red 3R was studied by the photocatalytic degradation under simulated sunlight irradiation. To study the effects of reflux time, pH and-concentration and reaction conditions of the synthesis process and properties of the materials, the optimum preparation conditions were found out. The results show that when the doping amount is 0.003 mol/L, the pH value is 6, the reflux time is 15 min, the photocatalytic activity of doped nanometer TiO₂ is the highest. The degradation rate of acid red 3R dye solution with the concentration of 50 mg/L was more than 98% after the sun exposure.

Key words: BF co-doped, nano TiO₂ emulsion, hydrolysis method, photocatalysis
