文摘

•: Nanotubes displayed lower adsorption efficiency than P25–TiO₂ and nanorods.
•: Ionic interactions between oppositely charged particles enhance adsorption rate.
•: Extra positive charge by Fe³⁺ and Pt⁴⁺ impregnation improved adsorption capacity.
•: Adsorption by various TiO₂ nanostructures fits Langmuir and frendluich isotherms.
•: Pt⁴⁺ loaded P25–TiO₂ exhibited highest EBT photodegradation efficiency.
