Solvothermal synthesis and photocatalytic performance of Mg2+-doped anatase nanocrystals with exposed {0Â 0Â 1} facets

- Mg2+ doped anatase nanoplates with {0 0 1} facets were prepared by solvothermal method.
- Mg2+ doping leads to vertically piling up of nanoplates creating large microcrystals.
- Magnesium doping shifts the absorption edge of TiO2 towards visible light region.
- Low Mg2+ doping enhances the photocatalytic activity for air pollutants oxidation.
