Research on Core-Shell TiO₂/Al₂O₃ by one-Step Hydrothermal

Abstract:

The core-shell structure’s synthesis process by one-step hydrothermal method has remarkable peculiarities, such as simple procedures and short production cycles. In order to get the precursor with the core-shell structure, it’s important to study the technological parameters. In this paper, the pH value, the concentration of AlCl₃,the mass ratio of core and shell , the hydrothermal temperature and time were detailed discussed. In order to get well-coated core-shell material, the technological parameters were the pH value=8.5-9.8, the concentration of AlCl₃ 0.040－0.050g/ml, Al₂O₃：TiO₂=10％－28.5％, the hydrothermal temperature 200°C and the hydrothermal time 3 hours.
