摘　　要：以ZrCl_(4)、H_(3)PW_(12)O_(40)(HPW)为原料,对苯二甲酸为配体,通过一锅水热法及热解法合成了金属有机框架UiO-66衍生的HPW@C-ZrO_(2)复合材料,利用FTIR、XRD、N2物理吸附、SEM及UV-Vis DRS对合成的复合材料的物理、化学性能进行表征,并以罗丹明B为目标污染物测试其光催化活性。结果表明,HPW的引入有效改善了材料的光催化性能;经过120min的可见光照射,HPW@C-ZrO_(2)对罗丹明B的降解效率达到86.7%。循环实验表明,该复合光催化剂表现出良好的稳定性。Metal-organic framework UiO-66-derived HPW@C-ZrO_(2) composites were synthesized by a hydrot-hermal method followed by a pyrolysis treatment using zirconium(IV)chloride and tungstophosphoric acid as raw materials,and terephthalic acid as ligand.The physical and chemical properties of the as-prepared composite materials were characterized by FTIR,XRD,N2 physisorption,SEM,and UV-Vis DRS,and Rhodamine B was used as the target pollutant to test their photocatalytic activity.The results showed that the introduction of HPW can improved the photocatalytic performance of original materials effectively.After a visible light irradiation for 120min,the degradation rate of HPW@C-ZrO_(2) to Rhodamine B reached 86.7%.Meanwhile,the cyclic experiments indicated that the composite photocatalytic material had good stability.
