氮掺杂纳米TiO2光催化降解弱酸性染料的研究
Study on photocatalytic degradation of weak acid dye with N-doped nano-TiO2
摘要
Abstract
N-doped nano-TiO2 photocatalyst was prepared by sol-gel method and characterized by X-ray diffraction (XRD) and ultraviolet visible light spectroscope (UV-Vis DRS). The visible light photocatalytic properties of the photocatalyst were investigated using Weak Acid Blue A dye solution as the target degrada-tion pol utant. The results showed that the particle size, content of anatase phase, and absorption band edge of photocatalysts were 16.5 nm, 98.7% and 618 nm, respectively, which had a higher absorption for ultraviolet and visible light. When the dosage of photocatalysts was 0.25 g, and the initial concentration and dosage of the weak Acid Blue A dye solution was 40 mg/L and 10.0 mL, the photodegradation rate of dye was 99.2%under 300 W metal halide lamp radiation for 240 min and the pH=2 or 12.关键词
