Characterization and Evaluation of the Efficiency of TiO2/Zinc Phthalocyanine Nanocomposites as Photocatalysts for Wastewater Treatment Using Solar Irradiation
Figure 2
Diffuse reflectance spectra of TiO2/ZnPc composites, prepared with
different percent in mass of ZnPc: (a) TiO2 P25. Composite containing:
1.0% of ZnPc (b); 2.5% of ZnPc (c); 5.0% of ZnPc (d); (e) composite containing 2.5%
of ZnPc (TiO2 P25 was used as reference), showing the Soret (370 nm)
and Q (683 nm) bands, typical of ZnPc; (f) diffuse reflectance spectrum of pure
ZnPc. Barium sulphate was used as reference for (a) to (d).
