Photocatalytic activity of magnetically anatase TiO2 with high crystallinity and stability for dyes degradation: Insights into the dual roles of SiO2 interlayer between TiO2 and CoFe2O4
A magnetically separable photocatalyst was synthesized with hollow structure. SiO2 interlayer can not only retard phase transition but increase crystallinity. Mechanisms of degradation of cationic and anionic dyes were studied respectively. Active species in photoreaction of dye wastewater have been deeply investigated.
