插层法制备g-C3N4/高岭石复合材料及其光学性能
Preparation of g-C3N4/kaolinite Composite by Intercalation Method and Its Optical Performance
摘要
Abstract
The surface and the interlayer of kaolinite has high activity and good normality which is so suitable for chemical modification, hence, the catalyst loading is worthy of in-depth study.Using methoxy-grafted kaolinite as precursor, the kaolinite-melamine composites were prepared by the displacement intercalation method.Then the kaolinite-melamine composite materials was calcined in the 550 ℃ to obtain the g-C3N4/kaolinite composite materials.The prepared composites were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetry and differential scanning calorimetry (TG-DSC), and their photocatalytic performance were also studied.It is indicated that it is difficult to synthesize g-C3N4 when kaolinite-melamine ratios are 1∶1 and 1∶2;while the composites with different ratios of g-C3N4 will be get when the mass ratio of kaolinite and melamine is 1∶3, 1∶4 and 1∶5, respectively.Kaolinite can effectively prevent the reunion of g-C3N4, and improved dispersion condition can be obtained due to the addition of kaolinite.The prepared g-C3N4 /kaolinite composites have good photocatalytic performance which has great significance in the research of mineral based economic, efficient and green catalyst.关键词
