Abstract

The liquid-liquid interfacial precipitation (LLIP) approach was used to synthesize the C60 fullerene nanowhisker (FNW)–CuS nanoparticle composites utilizing a CuS nanoparticle solution, C60-saturated toluene, and isopropyl alcohol (IPA). Powder X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were used to characterize the product of C60 FNW–CuS nanoparticle composites. These were also utilized to photocatalytic degradation of rhodamine B (RhB) under blue light emitting diode (LED) irradiation at 450 nm. Also, UV–vis spectroscopy was used to confirm the photocatalytic degradation activity of RhB over the C60 FNW–CuS nanoparticle composites. The percentage of photocatalytic degradation of RhB was shown to be 95.148%. The kinetics study for photocatalytic degradation of RhB using C60 FNW–CuS nanoparticle composites followed a pseudo-first-order reaction rate law. C60 FNW–CuS nanoparticle composites as photocatalyst have a rate constant of 4.82×10-2 min-1 at 25 °C.

C60富勒烯纳米晶须-CuS纳米粒子复合材料的制备及蓝光辐射降解罗丹明B的光催化剂

利用CuS纳米颗粒溶液、C60饱和甲苯和异丙醇（IPA），采用液-液界面沉淀（LLIP）方法合成了C60富勒烯纳米晶须（FNW）-CuS纳米颗粒复合材料。采用粉末X射线衍射（XRD）、拉曼光谱、扫描电子显微镜（SEM）和透射电子显微镜（TEM）对C60 FNW–CuS纳米颗粒复合材料的产物进行了表征。这些还用于在450nm的蓝色发光二极管（LED）照射下光催化降解罗丹明B（RhB）。此外，使用紫外-可见光谱证实了RhB在C60 FNW–CuS纳米颗粒复合材料上的光催化降解活性。RhB的光催化降解率为95.148%。使用C60 FNW–CuS纳米颗粒复合材料光催化降解RhB的动力学研究遵循伪一级反应速率定律。C60 FNW–CuS纳米颗粒复合材料作为光催化剂，在25°C下的速率常数为4.82×10-2 min-1。
