文摘
- •
The g-C3N4/TiO2-NTs electrode was synthesized by a simple dip-coating procedure.
- •
Simultaneous reduction of Cr(VI) and removal of organic pollutants was observed.
- •
Hydroxyl radicals and superoxide radicals were responsible for the oxidation removal.
- •
Photoelectrocatalysis mechanism under g-C3N4/TiO2-NTs electrodes was deduced.
- •
Modified electrode conducted with highly electron-hole separation efficiency.
