利用高压静电纺丝技术,制备具有微纳米尺寸并含羧基的电纺纤维。水热条件下负载SnS/SnS2异质结制备SnS/SnS2电纺纤维复合材料。利用SEM、XRD、XPS、TGA、UV-Vis等多种分析测试方法表征复合材料,SnS/SnS2异质结能均匀分布在电纺纤维上。利用氙灯模拟太阳光进行光催化实验,结果发现,从第一至第三周期,以SnS/SnS2异质结粉体为催化剂,体系的产氢量基本不变,而同等条件下以SnS/SnS2电纺纤维复合材料为催化剂,体系的产氢量明显增加;且复合材料在第三个周期中产氢的量是SnS/SnS2异质结粉体的1.34倍。
Electrospun fibers with micro-nano size and carboxyl groups were prepared by high-pressure electrospinning. Preparation of SnS / SnS2 Electrospun Fiber Composite under Hydrothermal Loading of SnS / SnS2 Heterojunction. The composite materials were characterized by SEM, XRD, XRD, TGA and UV-Vis. The SnS / SnS2 heterojunction could be uniformly distributed on the electrospun fibers. Using xenon lamp simulation of sunlight for photocatalytic experiments, the results show that from the first to the third cycle to SnS / SnS2 heterojunction powder as a catalyst, the system of hydrogen production basically unchanged, while under the same conditions SnS / SnS2 Electrospun fiber composites as catalyst, the system of hydrogen production increased significantly; and the amount of hydrogen in the third cycle of the composite material is 1.34 times the SnS / SnS2 heterojunction powder.
