摘要:
基于溶剂热法成功制备了BiOCl/UiO-66(Zr)-NH2(BUN)异质结复合材料,并通过XRD、TEM、SEM和DRS等对材料的晶相结构、表面形貌和光吸收范围等进行了表征. 光催化降解罗丹明B(RhB)实验结果表明,当BiOCl与UiO-66(Zr)-NH2的质量比为1:0.1,可见光照射20 min后,RhB的降解率高达98.5%,且材料循环使用4次后仍然具有良好的催化性能. 此外,结合复合材料的电化学性能、材料的自由基猝灭及电子自旋共振实验,揭示反应体系的光催化降解机理.
Abstract:
BiOCl/UiO-66(Zr)-NH2(BUN)heterojunction was successfully prepared by solvothermal method. The crystal structure,morphology and light absorption range of the material were characterized by XRD,TEM,SEM and DRS. The experimental results show that the degradation rate of RhB was the highest(98.5%)after 20 min visible light irradiation when the mass ratio of BiOCl to UiO-66(Zr)-NH2 was 1:0.1. After four cycles of the material usage,it still has a good RhB degradation property. In addition,the electrochemical performance of the composite material was explored. The material’s free radical quenching and electron spin resonance(ESR)experiments were also conducted to further propose the photocatalytic mechanism of the reaction system.
