摘要
采用水热法制备出Zn Sn(OH)6/石墨烯复合光催化材料,利用XRD、FT-IR、UV-vis DRS和BET对样品的结构和形貌进行了表征。以亚甲基蓝为模拟污染物考察了复合材料的光催化性能。结果表明,当石墨烯质量分数为3%时,Zn Sn(OH)6/石墨烯复合材料的光催化性能最优,紫外照射100 min后,对亚甲基蓝降解率达到98.1%,比纯Zn Sn(OH)6光催化活性提高了1.74倍。经过5次循环使用后依然有96.4%的降解率。Zn Sn(OH)6/石墨烯复合光催化材料对工业染料分散黄、活性红和酸性蓝也有很好的降解活性,说明Zn Sn(OH)6/石墨烯复合材料具有很好的普适性。
A high-efficiency ZnSn （OH）6/graphene nanocomposite photocatalyst is successfully prepared by a hydrothermal process. The as-prepared ZnSn（OH） 6/graphene is characterized by XRD, FT-IR, UV-vis DRS and BET. The photocatalytic activity and stability of ZnSn （ OH ） 6/graphene is evaluated through the photocleaning of methylene blue （MB）-containing wastewater under ultraviolet light irradiation. The results show that ZnSn （OH）6/graphene nanocomposite photocatalysts have higher photocatalytic activity and stability than the pure ZnSn （ OH ）6- The photodegradation rate of methylene blue is 98. 1% after UV-light irradiation for 100 minutes. After five cycles＇ photodegradation, the degradation rate of MB is still 96. 4% of the initial degradation. There are high degradation activity of ZnSn（OH）6/grapheme to the industrial dyes such as Disperse Yellow,Activity Red and Acid Blue, indicating ZnSn （OH） 6/graphene composites have a wide spectrum.
