Synthesis of Nanocrystalline Titania via Microwave-Assisted Homogeneous Hydrolysis Under Hydrothermal Conditions

摘要

In this paper, we report on a new procedure for nanocrystalline titania synthesis using microwave-assisted homogeneous hydrolysis under hydrothermal conditions. We show that this synthetic procedure promotes formation of low-aggregated TiO_2 powders with very high specific surface area (up to 240 m~2/g) and small particle size (5-7 nm), and that it hinders SO_4~(2-) ions' sorption on the surface ofnanoparticles.
