Visible light responsive sulfated rare earth doped TiO2@fumed SiO2 composites with mesoporosity: Enhanced photocatalytic activity for methyl orange degradation

- Visible light active mesoporous sulfated RE-doped TiO2@SiO2 have been developed facilely.
- The photocatalysts exhibited a mesoporous structure and anatase crystallites.
- The mesoporous sulfated 0.25%Nd3+-TiO2@fumed SiO2 exhibits the best photoactivities.
- The highest VL photodegradation rate of methyl orange is 90.05% after 40 h.
- The possible VL response photodegradation mechanism has also been proposed.
