摘要
利用十八胺和油胺表面修饰轴向溴代亚酞菁(SPc-Br),并将修饰后的SPc-Br作为光敏剂负载于二氧化钛(TiO_(2))表面,最终制备SPc-Br/TiO_(2)复合光催化剂。通过调整SPc-Br负载量获得不同质量配比复合光催化剂,并通过FT-IR、UV-Vis DRS、SEM及XPS等手段进行表征。通过催化材料在可见光下对有机染料溴酚蓝(BB)的降解效率评价其光催化性能。结果表明:经SPc-Br敏化后的TiO_(2)复合光催化材料在可见光区具有明显的光响应性,其在可见光下对溴酚蓝的降解效率是纯TiO_(2)的2.07—4.61倍。
Bromo-subphthalocyanine(SPc-Br)was firstly modified by octylamine and olamine.A series of SPc-Br/TiO_(2) composite photocatalyst was obtained by loading photosensitizer SPc-Br of different quality on the surface of TiO_(2).The prepared catalysts were characterized by FT-IR,UV-vis DRS,SEM and XPS.The photocatalytic performance was evaluated by the photocatalytic degradation rate of bromophenol blue(BB)under visible light.The results show that the modified TiO_(2) has obvious spectral response characteristic in visible light region,and its degradation efficiency of BB in visible light is 2.07-4.61 times than that of pure TiO_(2).
