Abstract
The Ce-UiO-66-NH2 material was successfully prepared by oil bath method, and TiO2 and PANI were compounded on the basis of it, which improved the degradation efficiency of rhodamine B (RhB). XRD, TEM, and XPS characterization confirmed that the composite material formed a core-shell structure and polyaniline was uniformly coated. The composite with 20 μL aniline and CTAB surfactant showed the highest degradation efficiency, and the degradation rate of RhB reached 99.90% within 60 min under ultraviolet light irradiation. The band alignment and free radical trapping experiments show that it follows the ternary Z-type heterojunction mechanism, \( \bullet {\kern 1pt} {\text{O}}_{2}^{ - }\) is the main active species. It provides a new idea for the design of high-performance photocatalysts and is of great significance for promoting the application of photocatalytic technology in water pollution control.
采用油浴法成功制备了Ce-UiO-66-NH2材料，并在此基础上复合了TiO2和聚苯胺，提高了罗丹明B （RhB）的降解效率。XRD、TEM、XPS表征证实复合材料形成核壳结构，聚苯胺被均匀包裹。以20 μL苯胺和CTAB为表面活性剂的复合材料对RhB的降解效率最高，对RhB的降解率达到99.90％% within 60 min under ultraviolet light irradiation. The band alignment and free radical trapping experiments show that it follows the ternary Z-type heterojunction mechanism, \( \bullet {\kern 1pt} {\text{O}}_{2}^{ - }\) is the main active species. It provides a new idea for the design of high-performance photocatalysts and is of great significance for promoting the application of photocatalytic technology in water pollution control.
