dc.description.abstractThe inhibition of electrons-holes recombination and enhancement of visible light photocatalytic activitywere accomplished by the synthesized TiO2/CS nanocomposites system. In this present work, the differentweight ratio of TiO2and 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 systemwere characterized via FT-IR, TEM and XRD measurements. The band gap of the prepared materials andits excitation and emission spectra were elevated through UV–vis and PL analyses. Moreover, the MO andMB degradation capability of the synthesized TiO2/CS nanocomposites was optimized, and the outcomesare described in detail.
