Enhanced visible photocatalytic activity of TiO2 hollow boxes modified by methionine for RhB degradation and NO oxidation

N and S co-doped TiO2-hollow nanoboxes assembly from high energy TiO2 nanosheets were prepared by calcining the mixture of TiOF2 cubes and methionine (C5H11NO2S), which showed improved visible photoreactivity in RhB degradation and NO oxidation.
