以NaCl为Cl源,采用水热法,于聚偏氟乙烯/苯乙烯-顺丁烯二酸酐共聚物/纳米石墨(PVDF/SMA/石墨)电纺纤维表面先后分别负载了Cl-TiO_2和CdS,得到CdS@Cl-TiO_2/(PVDF/SMA/石墨)纤维复合材料。利用SEM、TEM、XRD、XPS、UV-Vis和TGA对复合材料进行了表征。讨论了氙灯模拟太阳光条件下,复合材料催化水制氢的光催化性能。结果表明:CdS@Cl-TiO_2/(PVDF/SMA/石墨)复合材料的平均产氢速度为77.2mL/(h·gcatalyst),且重复利用性好;同等条件下,光催化效率明显优于未掺Cl的复合光催化剂。
Using NaCl as Cl source and hydrothermal method, the surface of polyvinylidene fluoride / styrene-maleic anhydride copolymer / nano-graphite (PVDF / SMA / graphite) electrospun fibers were respectively loaded with Cl-TiO 2 and CdS , CdS @ Cl-TiO_2 / (PVDF / SMA / graphite) fiber composites were obtained. The composites were characterized by SEM, TEM, XRD, XPS, UV-Vis and TGA. The photocatalytic activity of hydrogenation catalyzed by composite materials under xenon lamp simulated sunlight was discussed. The results show that the average hydrogen evolution rate of CdS @ Cl-TiO_2 / (PVDF / SMA / graphite) composites is 77.2mL / (h · gcatalyst), and the recyclability is good. Under the same conditions, Mixed with Cl photocatalyst.
