摘要:
以氧化石墨烯(GO)、Zn(NO3)2·6H2O和SnCl4·5H2O为起始原料,采用水热合成法制备ZnSn(OH)6/GO复合材料。通过X射线衍射(XRD)、 透射电子显微镜(TEM)对材料结构进行表征,并对ZnSn(OH)6/GO复合材料形成机理进行了探讨。以亚甲基蓝(MB)作为模拟污染物,对复合材料的光催化活性进行了探讨。结果表明:与氧化石墨烯复合后,ZnSn(OH)6光催化活性和光稳定性明显提高。紫外光辐照120 min后,ZnSn(OH)6/GO复合材料对MB的降解率达到了98.1%; 重复使用6次后, ZnSn(OH)6/GO复合材料对MB的光催化降解率仅降低了8.9%。
Abstract:
ZnSn(OH)6/GO composites were synthesized via hydrothermal method using GO,Zn(NO3)2·6H2O and SnCl4·5H2O as raw materials.The as-prepared samples were characterized by X-ray diffraction(XRD)and Transmission electron microscopy(TEM).The formation mechanism of ZnSn(OH)6/GO composites was discussed in the paper.The photocatalytic activity of prepared ZnSn(OH)6/GO composites was evaluated by photocatalytic degradation of Methylene Blue(MB)under UV irradiation. The results indicated ZnSn(OH)6/GO composites had better photocatalytic activities and stabilities under UV irradiations.After 120 min UV irradiation, the photocatalytic degradation rate of ZnSn(OH)6/GO composites for MB reached 98.1%.After six successive cycles, their photocatalytic activities for degradation of MB only decreased by 8.9%.
