Surfactant induced copper vanadate (β-Cu2V2O7, Cu3V2O8) for different textile dyes degradation

Abstract

In this study, pristine β-Cu2V2O7, CTAB-β-Cu2V2O7 and PVP–Cu3V2O8 were synthesized via hydrothermal method. The synthesized brown powder samples were exemplified using XRD, UV, PL, Raman and SEM studies. Further with XRD, we confirmed that the impurities were eradicated in addition of surfactant PVP. The bandgap obtained were 3.09 eV, 2.97 eV and 2.28 eV for β-Cu2V2O7, CTAB-β-Cu2V2O7 and PVP–Cu3V2O8. The morphology of β-Cu2V2O7 was found to be cluster of nanoparticles with high level of agglomeration. While adding the surfactants (CTAB, PVP) the nano platelets were grown and uniformly arranged. The PVP-Cu3V2O8 sample exhibited 96%, 77% and 96% efficiency on reducing Methylene Blue, Rhodamine B and Malachite Green dyes. The enhancement of attaining complete efficiency by the PVP–Cu3V2O8 photocatalyst is attributed by the appropriate phase of host material and the PVP itself acted as a trapper for electron and hole which induced the rate of degrading toxic pollutants. The PVP–Cu3V2O8 photocatalyst will be enthusiastic and optimized aspirant for reducing organic pollutants and for wastewater management in future days.
