文摘
- •
Anatase TiO2 NPs were uniformly deposited on monodisperse Fe3O4 to form core–shell Fe3O4@TiO2 by non-thermal process.
- •
The main feature is direct deposition of anatase TiO2 NPs under mild condition, thus avoiding any high temperature treatment.
- •
Evenly distributed Au NPs on TiO2 significantly increased its photocatalytic activity.
- •
Superparamagnetic Fe3O4 cores could greatly facilitate the separation of the photocatalyst from the treated water.
