糠醛/8-羟基喹啉铝聚合物复合纳米TiO2光催化剂的研究

通过糠醛／8-羟基喹啉铝聚合物(PFQ)与纳米TiO2的复合制得了光活性很高的催化剂，并通过FTIR，UV-Vis，ESR等手段对光催化剂进行了表征．结果表明糠醛／8-羟基喹啉铝聚合物与纳米TiO2复合后，拓宽了纯纳米TiO2的光谱响应范围，使光催化剂在可见光范同都有很强的吸收．并用该催化剂对甲基橙进行了光降解反应，实验表明在自然光下，该催化剂十几分钟就能使甲基橙染料完全褪色．

Study of photocatalyst coated nanometer TiO2 with furfural and oxine-Al3+ polymer

Photocatalyst coated nanomeyer TiO_2 with furfural and oxineoAl~(3+) polymer was synthesized using an acid-catalyzed method and characterized by IR, UV-vis and ESR techniques. The results show that the catalysis activity of the photocatalyst of furfural and oxine-Al~(3+) polymer/nanometer TiO_2 complex after calcinations was higher than pure TiO_2 and polymer. The aimed catalyst has been found to be modifying the nanometer TiO_2 with furfural and oxine-Al~(3+) polymer, resulting in the shift of the absorption band to longer wavelength regions, i. e. into the visible light region, whereas pure TiO_2 absorb ultraviolet rays(<380 nm) only. Furthermore studies showed that the photocatalyst employed in this paper could depigmentize methyl orange solution in a few minutes under visible light. Furfural and oxine-Al~(3+) polymer/TiO_2 complex after calcinations was a photocatalyst with high catalytical activity.
