Photocatalysis and Bandgap Engineering Using ZnO Nanocomposites

Figure 5

(a) UV-Vis diffuse reflectance spectra of nanofibers: (A) TiO₂/ZnO-1, (B) TiO₂/ZnO-2, (C) TiO₂/ZnO-3, and (D) pure TiO₂ [168]. (b) Photocatalytic degradation of RhB in an aqueous solution in the presence of nanofibers [168]. (c) Effect of ZnO nanoflowers, pristine titanium oxide nanofibers (TiO₂), titanium oxide nanofibers incorporating ZnO NPs (ZnO doped TiO₂), and the newly introduced ZnO/titanium oxide nanostructure on the photocatalytic degradation of RhB dye [170]. (d) Ultraviolet-visible absorption spectra of pure ZnO, TiO₂, and ZnO/TiO₂ [176]. (e) Photocatalytic degradation of MO by various photocatalysts.
