摘要
以四方酸与2-甲基喹啉为原料合成2,4-双(4-甲基喹啉基-3-甲基)环丁二烯-1,3-二甲醚方酸菁染料(简称DQCB),并制备了响应日光的DQCB敏化的nano-TiO2复合催化剂。利用MS、EA、H1-NMR和FT-IR确定其化学结构;以UV-VisDRS研究其光谱响应性质;并以GC为检测手段研究了DQCB敏化的nano-TiO2复合催化剂日光催化气体苯的活性。研究表明:DQCB对光子能量的吸收范围为200～800nm,且吸光能力强;日光下反应78h,DQCB-nano-TiO2复合物1对苯的降解率为97.69%,较纳米TiO2提高36.96%。
2,4-bis（4-methylquinolin-3-yl） cyclobuta-1,3-diene-1,3-dimethoxy（DQCB） was synthesized with 2-methyl quinoline and squaric acid.It was used as dye to prepare DQCB sensitized nano-TiO2 catalyst which can work in sunlight.The structure of DQCB was confirmed by MS,EA,H1-NMR and FT-IR spectroscopy,and diffuse reflectance spectra was used to characterize the optical property.The benzene removal of DQCB-nano-TiO2 complex catalyst was determined by gas chromatography.Results show that the DQCB has an intense absorption in the light region of 200-800 nm.The benzene removal of DQCB-nano-TiO2 complex catalyst for 78h was 97.69%,and it was 36.96% higher than that of nano-TiO2.
