摘要:
采用微波液相法制备了CeO2/凹凸棒石(ATP)/MoS2三维复合材料,用X射线衍射、傅里叶变换红外光谱、紫外-可见漫反射光谱、原位透射电子显微镜等手段对其进行表征,以苯并噻吩为模拟含硫污染物探讨了CeO2/ATP/MoS2对模拟FCC 汽油的光催化氧化脱硫活性,研究CeO2和MoS2质量比对光催化剂活性的影响。结果表明,ATP骨架与CeO2和MoS2形成稳定三维网络结构,能有效增加复合光催化剂的表面积,在空间上形成多渠道的电子传递通道,促进光生载流子的分离。模拟太阳光连续照射2 h,当CeO2与 MoS2质量比为4/10时,CeO2/ ATP/MoS2复合材料对模拟汽油脱硫率高达92%。
Abstract:
Ternary CeO2/attapulgite(ATP)/MoS2 composites were synthesized by microwave assisted synthetic method. The structures of the composites were characterized by X-ray diffraction, fourier-transform infrared, ultraviolet-visible diffuse reflectance and in situ transmission electron microscope. The photocatalytic activities of CeO2/ATP/MoS2 composites were investigated by degradating benzothiophene in model gasoline under solar irradiation. The effect of the mass ratio of CeO2 to MoS2 on photocatalytic activity was investigated. The results indicate that three-dimensional network structure is constructed by ATP skeleton, CeO2 particles and MoS2 nanosheet, which can effectively increase the surface area of the composites and promote the separation of electrons and holes by resulting electronic transmission channels of multi-channel in space. The degradation rate of benzothiophene can reach 92% under 2 h irradiation when the mass ratio of CeO2 to g-C3N4 is 4/10.
