摘要
以TiO_(2)纳米花(TNF)为基底,原位合成了UiO-66@TNF/Ti复合光电极,并进一步通过氨基修饰提升了其催化性能.通过一系列的表征证明,氨基的引入有利于提升复合光电极的光电性能.降解实验结果表明,经过氨基修饰的UiO-66-NH_(2)@TiO_(2)光电极表现出优于未修饰TNF/Ti光电极的催化性能.氨基的引入显著拓宽了光电极的光吸收范围,增强了其光催化活性.在初始浓度为5 mg/L、pH值为7.0且施加2.0 V偏置电压的条件下,UiO-66-NH_(2)@TiO_(2)光电极对罗丹明B的降解效率达到了93.74%.
In this study,a UiO-66@TNF/Ti composite photoelectrode was insitu synthesized using TiO_(2)nanoflowers(TNF)as the substrate,and its catalytic performance was further enhanced by amino modification.A series of characterizations demonstrated that the introduction of amino groups was beneficial to improving the photoelectric performance of the composite photoelectrode.The degradation experiments indicated that the UiO-66-NH_(2)@TiO_(2)photoelectrode,after amino modification,exhibited superior catalytic performance compared to the unmodified TNF/Ti photoelectrode.The introduction of amino groups significantly broadened the light absorption range of the photoelectrode and enhanced its photocatalytic activity.Under the conditions of an initial concentration of 5 mg/L,pH 7.0,and an applied bias voltage of 2.0 V,the degradation efficiency of Rhodamine B by the UiO-66-NH_(2)@TiO_(2)photoelectrode reached 93.74%.
