Abstract

ABSTRACT. In the current study, a novel visible light-active photocatalyst CuS/TiO2 nanocomposite was synthesized by a template-free hydrothermal method. Fourier transform infrared spectroscopy (FTIR) confirmed the formation of synthesized nanocomposites and the structural characteristics of synthesized nanoparticles were characterized and confirmed by the X-ray diffraction (XRD) technique. The morphology and particle size of synthesized nanocomposites were measured by a field emission scanning electron microscope (FESEM), which revealed an average particle size of around 30 nm. The optimized efficiency of the fabricated photocatalyst was assessed for the photodegradation of rhodamine B (RhB) dye. It was observed that the photodegradation efficiency of CuS/TiO2-Y composites having a molar ratio of 1:1 for RhB was found to be 89.54% under visible light irradiation.

新型pn -异质结cu /TiO2纳米复合材料在可见光下光催化降解罗丹明B染料的制备

摘要本研究采用无模板水热法制备了一种新型可见光活性光催化剂cu /TiO2纳米复合材料。傅里叶变换红外光谱(FTIR)证实了合成的纳米复合材料的形成，并用x射线衍射(XRD)技术对合成的纳米颗粒的结构特征进行了表征和证实。利用场发射扫描电镜(FESEM)测量了合成的纳米复合材料的形貌和粒径，发现其平均粒径约为30 nm。考察了优化后的光催化剂对罗丹明B染料的光降解效率。结果表明，在可见光照射下，物质摩尔比为1:1的cu /TiO2-Y复合材料对RhB的光降解效率为89.54%。关键词:cu /TiO2纳米复合材料，异质结结构，罗丹明B，光降解，可见光照射;公牛。化学。Soc。中国生物医学工程学报，2016,37(6):1553-1564。DOI: https://dx.doi.org/10.4314/bcse.v37i6.19
