Description
一技术领域
本发明涉及复合材料领域,具体涉及一种氧化石墨烯/二硫化锡复合材料的制备方法。
二背景技术
含六价铬离子的工业废水以排放量大、难降解、有机物含量高等特征成为废水治理工艺中的难点。半导体光催化技术作为一种高效、绿色的具有广阔应用前景的水处理技术,日益受到人们的重视(LIU Zi-li,LIU Hong-wei,LI Ru.Photocatalytic reductionof waste water containing Cr(VI)byphotocatalyst Cu2O[J].J Chem Eng of ChineseUniv,2007,21(1):88-92.; Xu Y H,Liang D H,Liu M L,et al.Preparation andcharacterization of Cu2O-TiO2:efficient photocatalytic degradation ofmethyleneblue[J].Mater Res Bull,2008,43(12):3474-3482.)。在诸多半导体光催化材料中,SnS2由于其效率高、能耗低、成本低、应用范围广以及二次污染少等特点在光催化领域具有广阔的应用前景(Zhang Y C,Du Z N,Li K W,Zhang M.Size-controlledhydrothermal synthesis of SnS2 nanoparticles with high performance in visiblelight-driven photocatalytic degradation of aqueous methylorange.Sep.Purif.Technol.2011,81, 101-107)。但SnS2的光催化活性受到光生电子与空穴的高复合率较低、可见光的利用率、易团聚等因素的制约,因此如何提高其光催化活性是人们普遍关心的问题。其中,非金属碳掺杂被认为是一种很好的扩展半导体催化剂响应区域的方法,氧化石墨烯作为一种蜂窝状晶格结构的新型碳质材料,具有独特的二维表面结构、良好的导电性能和较大的比表面积。本发明采用水热合成法制备了SnS2,并以氧化石墨烯(GO)为载体和包覆材料,制得氧化石墨烯 /二硫化锡复合材料.(GO@SnS2),其中GO作为电子受体能够抑制光生电子-空穴的复合,提高了复合材料的光催化活性。
