Metalloporphyrin modified defective TiO₂ porous cages with the enhanced photocatalytic activity for coupling of hydrogen generation and tetracycline removal.

ABSTRACT: Integration of molecular transition-metal complexes and semiconductors is an appealing method to develop high-performance hybrid photocatalysts based on improvement of their solar energy harvesting ability and photogenerated charge carrier separation efficiency. Herein, Cu-TCPP modified TiO₂ porous cages with oxygen vacancy defects, derived from NH₂-MIL-125(Ti) nanocrystals, are successfully prepared to form PC-TiO₂-d/Cu-TCPP hybrids via a surface assembly process. The PC-TiO₂-d/Cu-TCPP hybrid shows an enhanced photodegradation efficiency (73.7%, 95.4%) towards tetracycline in the air under visible light or the simulated sunlight irradiation compared to PC-TiO₂-d (33.7%, 81.1%) within 100 min. Moreover, the
