Abstract

The mesoporous TiO₂ nanoparticulate has been prepared by evaporation induced self-assembly method using EO-PO type polyether P123 as a template. The small angle X-ray diffraction, wide angle X-ray diffraction, high-resolution transmission electron microscopy and N₂ isothermal adsorption-desorption are used to study the microstructure and morphology of the as-synthesized mesoporous TiO₂. The results demonstrate that the mesoporous TiO₂ belongs to anatase and the size is 20-30 nm. The sample is prepared using P123 as a template with average pore size distribution of 11.54 nm, specific surface area of 84.83 m²/g and pore volume of 0.234 cm³/g. The as-synthesized mesoporous TiO₂ exhibits remarkably high photocatalytic activity of 93.6 % in decomposing formaldehyde under ultraviolet light irradiations for 90 min. This work provides a basic experimental process for the preparation of mesoporous TiO₂, which will possess a broad prospect in terms of the applications in improving indoor air quality.
