文摘
- •
RGO decorated raspberry-like TiO2 microspherical composites were synthesized.
- •
RGO-TiO2 composites showed photocatalytic reduction of Cr(VI) under visible irradiation.
- •
The best photocatalytic reduction of Cr(VI) was observed for the composite of 5 wt% rGO decoration.
- •
Enhanced photocatalytic activity was due to extended wavelength region and quicker transfer of electrons.
