Facile preparation of novel organic-inorganic PI/Zn0.25Cd0.75S composite for enhanced visible light photocatalytic performance

- Novel PI/Zn0.25Cd0.75S composite showed enhanced activity in dye degradation.
- The composites PIZCS-30 exhibited the best activity.
- The heterojunction was in situ fabricated between PI and Zn0.25Cd0.75S.
- The PI/Zn0.25Cd0.75S heterojunction facilitated the separation of electron-hole pairs.
