| 摘 要： | 采用硬脂酸法制备K2La2Ti3-xCexO10本体。分别采用微波辅助法和水浴法对K2La2Ti3-xCexO10进行质子交换、胺柱撑和硫化镉插层，制备了硫化镉插层K2La2Ti3-xCexO10催化剂。用X射线衍射（XRD）、扫描电镜（SEM）和紫外-可见漫反射（UV-vis）等手段对复合催化剂的晶型、粒径、表面形貌等进行表征，考察催化剂的可见光催化分解有机物活性。结果表明：在K2La2Ti3-xCexO10层间插入硫化镉可以将催化剂的光谱响应范围拓展到可见光区，提高了光催化降解有机物活性。水浴法制备的CdS-K2La2Ti3-xCexO10降解罗丹明B的降解率可以达到17.68%，而采用微波法制备的CdS-K2La2Ti3-xCexO10降解罗丹明B的降解率可以达到33.66%。

| Abstract: | The Ce-doped-K2La2Ti3O10（K2La2Ti3-xCexO10） was prepared via a stearic acid method，and CdS-intercalated K2La2Ti3-xCexO10 photocatalysts were prepared by microwave irradiation and water bath method，respectively.The crystal shape，particle size，and morphology of the samples were characterized by X-ray diffractometer（XRD），electronic scanning
electron microscopy （SEM），and UV-visible spectroscopy instrument （UV-vis）.The photocatalytic properties of these cata-
lysts for degradation of organics were also investigated.Results showed that，the intercalation of CdS expanded the absorption range to visible light，and the photocatalytic activity was enhanced.The photocatalytic activity of microwave-assisted CdS-K2La2Ti3-xCexO10 for the degradation of Rhodamine B was 33.66%，whereas the degradation of water bath prepared ones was 17.68%.
