Titanium dioxide (TiO2) is a wide bandgap semiconductor that has range of applications including wastewater treatment, photocatalysis, solar cells, and sensors owing to its excellent electronic optical properties. However, the TiO2 (∼3.2 eV) along with recombination processes photoexcited charge carriers reduce interfacial transport properties respective activities. Energetics, response, corresponding photophysics excited can be altered through doping codoping composite formulation. Therefore, it very crucial understand structure–property property-application relationships doped, co-doped, maximize efficiency extend fundamental understanding for their in different fields. In this Perspective, we summarize ongoing research on advancement undoped, structure morphology, energetics, relative water-splitting reactions. We then propose our perspectives future potential energetic manipulation photocatalytic develop advanced highly efficacious catalytic materials.

Abstract Herein, Ag/TiO 2 /Nylon 6/PMMA catalyst system was developed, and its photocatalytic properties were fully analyzed. XRD, SEM, EDS, PL analyses carried out to get information on crystal structure, micromorphology, elemental composition, band gap energy. Photocatalytic degradation followed by UV–vis spectrophotometry. The of the found be between 2.51 3.1 eV. Up 80% achieved under UV light irradiation. No bulk adsorption observed, which means that reaction completely process. pH 3 value determined suitable for a high rate. Reaction kinetic matched with first-order rate law. newly developed polymer blend matrix here may have broad application prospects in remediation water resources.
