Resumen

The inhibition of electrons-holes recombination and enhancement of visible light photocatalytic activity were accomplished by the synthesized TiO₂/CS nanocomposites system. In this present work, the different weight ratio of TiO₂ and chitosan (75:25, 50:50 and 25:75) nanocomposites were synthesized via two-step method. After that, the existing functional groups, size and structure of the nanocomposites system were characterized via FT-IR, TEM and XRD measurements. The band gap of the prepared materials and its excitation and emission spectra were elevated through UV–vis and PL analyses. Moreover, the MO and MB degradation capability of the synthesized TiO₂/CS nanocomposites was optimized, and the outcomes are described in detail.
