Fabrication, characterization and application of a reusable immobilized TiO2-PANI photocatalyst plate for the removal of reactive red 4 dye

- A novel immobilized P-25 TiO2/PANI/ENR/PVC composite on a glass plate was fabricated.
- PANI formed a core-shell coating on TiO2 with an optimum thickness of 0.9 nm.
- PANI lowered the bandgap energy and ecb and h+ recombination of TiO2.
- P-25 TiO2/PANI/ENR/PVC is visible light active with enhanced photocatalytic activity.
- Immobilized composite can be recycled sustainably over extended applications.
