Enhanced Cr(VI) Photocatalysis Reduction by Layered N‐doped TiO2 Sheets from Template Free Solvothermal Method

Layered TiO2 sheets with high Cr(VI) photoreduction ability were prepared by template free solvothermal method using ethylene glycol (EG) as structure directing agent. EG linking function in the layered confirmed SEM, TEM, FTIR, XPS and so on. Moreover, obtained large sized (20~50 μm length, about 5~10μm width) assembled N‐doped thin 1.2nm gap between, resulting very surface area (327.5 m2/g) abundant Ti3+ sites for adsorption reduction. This can not only have good performance during photocatalysis reduction application (Cr(VI) removal rate: 0.84 mg*g‐1*min‐1), but also endow material cycle ability.
