Preparation of Bionic TiO₂ Structure Using Aquatic Plants as Template

Abstract:

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 nanoparticles with size of about 10 nm. The product was studded with piled pores which had a few to dozens of nanoaperture. 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.
