Increasing the photocatalytic efficiency of ZnWO4 by synthesizing a Bi2WO6/ZnWO4 composite photocatalyst

In the present study, a Bi2WO6/ZnWO4 photocatalyst was successfully constructed by modified hydrothermal synthesis method with di?erent molar concentrations of Bi2WO6 respect to ZnWO4. The variation in changed photocatalytic properties catalyst. synthesized characterized various techniques decipher its structural and spectral properties. interaction Bi2+ ionic charge carriers many-body effects cause band gap narrow Bi2WO6/ZnWO4, as shown PL analysis. decrease energies (Eg) from 4.7 eV (ZnWO4) 3.5 (30% Bi2WO6/ZnWO4) is beneficial because less energy required excite valence electrons. maximum degradation Plasmocorinth B dye found 30% under UV irradiation. This increased activity can be attributed (i) synergistic effect bicrystalline framework ZnWO4, (ii) high close contact between (iii) small crystallite size. shows significant potential water/wastewater treatment application.
