- •
TNS composed of anatase and titanate synthesized via a facile one-step method.
- •
Cr(VI) and 4-CP can be simultaneously removed by TNS through photocatalysis.
- •
Photocatalytic efficiencies of Cr(VI) and 4-CP greatly enhanced when coexisting.
- •
Synergetic promotion effect occurs due to separation of electron-hole pairs.
- •
Autosynchronous doping after Cr(III) adsorption leads to narrowed energy gap.
