TiO2 Quantum Dots Supported on Poly(Chloroaniline): Enhanced Photocatalytic Degradation and Recyclability for Wastewater Treatment
A poly(chloroaniline)/TiO2 quantum-dot (ClAn/TiQD) hybrid photocatalyst was prepared by in situ oxidative polymerization to address the limited visible-light utilization and charge recombination commonly associated with TiO2-based systems in dye-bearing wastewater treatment. Structural and spectroscopic analyses confirmed retention of anatase TiO2 after hybrid formation, preservation of the conjugated polymer backbone, and interfacial coupling between TiQD and ClAn. TEM showed ClAn particles of 33–42 nm, TiQD domai …
