Preparation of Bionic TiO2 Structure Using Aquatic Plants as Template

摘要：

　　The bionic structure nanoporous TiO2 materials were prepared using aquatic plants as biological templates.The X-ray diffraction (XRD),field emission scanning electron microscopy (FESEM),high resolution transmission electron microscopy (HRTEM),nitrogen adsorption method and ultraviolet-visible light spectrometer were employed to characterize the structure of samples and the degradation performance of methylene blue solution under the visible light.The results showed that TiO2 sample inherited the porous structure of original template.Such bionic material was composed of ultra-thin piece layers which were full of TiO2 nano-particles with size of about 10 nm.The product was studded with piled pores which had a few to dozens of nano aperture.The material was doped with a small number of bionic legacy elements which can enhance the absorption of 400-800 nm range of the visible light,thus the bionic nanoporous TiO2 materials had better photocatalytic degradation effects of methylene blue solution in the sun.
