- 摘要:
- 利用溶剂热法制备了MIL-101（Fe）材料，通过扫描电镜表征了材料的形貌。采用光催化实验，以亚甲基蓝作为指示剂，探究了亚甲基蓝浓度，催化剂用量和时间三个因素对材料的降解率的影响，分析了以MIL-101(Fe)进行光催化降解的最佳条件，并在暗室和紫外光照环境下进行了空白试验和对照实验。结果表明，制备的材料拥有金属介空结构的微观结构和特殊形貌，形成了多级结构。在6 mg/L的亚甲基蓝溶液中，当MIL-101（Fe）用量为1 g/L，降解时间为210 min时，降解率可达最大值92.5%。空白试验和对照实验结果表明，亚甲基蓝溶液的自降解率为7.025%，MIL-101（Fe）对亚甲基蓝的吸附率为34.1%，即MIL-101（Fe）的实际光催化效率为51.375%。该结果表明MIL-101 (Fe)具有较好的光催化性能，其在有机污染物的降解等环境保护方面有着极大的应用潜力。
- Abstract:
- MIL-101(Fe) material was prepared by solvothermal method and its morphology was characterized by scanning electron microscopy. The photocatalytic properties of the materials were tested. The influence of methylene blue concentration, catalyst dosage and time on the degradation rate was studied by using methylene blue as indicator and the optimum conditions of photocatalytic degradation of MIL-101(Fe) were analyzed. Blank experiment and control experiment were carried out in dark room and ultraviolet light. The results show that the prepared materials have the microstructure and special morphology of metal mesostructure, forming a multi-level structure. In 6 mg/L methylene blue solution, when the dosage of MIL-101(Fe) is 1 g/L and the degradation time is 210 min, the maximum degradation rate is 92.5%. The results of blank experiment and control experiment show that the self degradation rate of methylene blue solution is 7.025%, the adsorption rate of MIL-101(Fe) to methylene blue is 34.1%, that is, the actual photocatalytic efficiency of MIL-101(Fe) is 51.375%. This result show that MIL-101 (Fe) has preferable photocatalytic performance and great application potential in environmental protection such as degradation of organic pollutants.
