摘要:
为提高铁基金属–有机框架材料MOF(Fe)的重复使用性能,以均苯三甲酸、硫酸亚铁、活性碳纤维(ACF)为原料,采用室温原位生长法制备了铁基金属–有机框架材料/活性碳纤维复合材料MOF(Fe)/ACF。借助傅里叶红外光谱仪、扫描电子显微镜、能谱仪、X射线衍射仪对复合材料的结构、形貌、元素组成等进行了表征;测试了复合材料在不同条件下对50 mg/L活性黑KN–B染液的脱色效果,并探讨了光催化降解染料的机制。结果表明:黑暗条件下,分别在不加双氧水和加入0.12 mL/L双氧水时反应60 min后,MOF(Fe)/ACF对活性黑KN–B染液的脱色率分别为64.7%和80.2%;在1 000 W氙灯光照下,加入0.12 mL/L双氧水反应60 min后,MOF(Fe)/ACF 对活性黑KN–B染液的脱色率达95.7%,比ACF高52.2%;重复使用5次,MOF(Fe)/ACF对活性黑KN–B染液的脱色率仍可达86.0%。
