Photocatalytic degradation 4–CP 5 × 10^–5 mol L^–1 under simulated solar light irradiation assisted by TiPA and their composites with Cu₂O, V₂O₅, and CdS (Controls: 4–CP and TiO₂–anatase): Performance (C/C₀) of TiPA–A (a) and TiPA–B (b), based photocatalysts. Rate of photodegradation (%) after 120 min irradiation, assisted by TiPA–A and TiPA–B, alone and by their composites with sensitizers (c). Kinetics of photodegradation assisted by TiPA–A and TiPA–B and their composites with V₂O₅ (d).
