Hydrothermal synthesis and visible-light-driven photocatalytic degradation for tetracycline of Mn-doped SrTiO3 nanocubes

- The Mn-doped SrTiO3 samples were synthesized by a hydrothermal method.
- The Mn4+ doping can greatly enhance photocatalytic activity for tetracycline degradation under visible light irradiation.
- Characterization of Mn doped SrTiO3 by HRTEM-STEM.
- The possible photocatalytic mechanism of tetracycline degradation is determined by active species trapping experiments and ESR analysis.
