摘要:
二硫化锡（SnS2）的光生载流子复合严重，三氧化钨（WO3）的可见光吸收能力较弱，易导致SnS2与WO3的光催化活性较低。以四氯化锡为锡源、硫脲为硫源、钨酸钠为钨源，通过两步水热法制备了异质结WO3/SnS2复合材料，并研究了SnS2、WO3和WO3/SnS2复合材料的结构组成、微观形貌、光学性能以及光催化活性。结果表明：WO3/SnS2复合材料不仅有着较高的比表面积，同时其光生载流子的分离及输运良好。降解亚甲基蓝测试以及还原重铬酸钾测试表明：WO3/SnS2复合材料为Z型异质结结构，其光催化性能相较于SnS2与WO3有显著提高。在模拟太阳光照射下，WO3/SnS2复合材料降解亚甲基蓝的速率约为SnS2的34倍、WO3的25倍；WO3/SnS2复合材料还原重铬酸钾的速率约为SnS2的34倍、WO3的350倍。该制备所得WO3/SnS2复合材料具有较强的光催化活性，有望广泛应用于废水处理领域。
