In this study, porous N, Si-codoped TiO₂ hollow microsphere photocatalysts have been prepared by a facile aerosol flow synthesis method. The prepared photocatalysts were characterized by XRD, SEM, TEM, UV–vis DRS, and XPS. The results indicated that both nitrogen doping and formation of Ti–O–Si bond happened in the N, Si-codoped TiO₂ hollow microspheres, leading to an enhanced visible-light driven photocatalytic performance on degradation of salicylic acid compared with pure TiO₂ and single N or Si doped TiO₂ counterpart catalysts.
