摘要

Nanomorphological anatase TiO(2) from spongy network to porous nanoparticles was synthesized by a modified sol-gel preparation and a post microwave-assisted combustion treatment. The TEM studies showed that the spongy network texture was resulted in sample calcined at lower temperature (360 degrees C) and the structure partially collapsed into solid and porous nanoparticles when calcined at higher temperature (400 degrees C). The photocatalysis study showed that the lower calcinations sample is photo-inactive large adsorbed of methyl orange than P25. The special texture, large adsorption of organ molecular and photo-inactivity of the lower calcinations sample indicated that the materials maybe served as a kind of promising biomimetic material.
