文摘
- •
Ni and Pt NPs are hosted by the TiO2 framework in the form of small nanoparticles.
- •
The composites show large surface areas ca. 200 m2/g and reduced band gap energies.
- •
Photodegradation of RhB in aqueous medium has been investigated under UV–vis light.
- •
The presence of 1 wt% Ni, Pt NPs significantly enhances the photocatalytic activity.
- •
Ni nanocomposite presents ferromagnetic behavior and exhibits the best stability.
