| Tartalmi kivonat: | The copper-modified zeolite (Z-Cu) prepared by an ion-exchange process was characterized by X-ray diffraction, DRS spectroscopy, SEM microscopy and EDX analysis. The XRD analysis indicated the reduction of the peak intensity corresponding to Na+ presence as a consequence of ion exchange process between Na+ and Cu2+. The presence of copper into Z-Cu was confirmed by EDX analysis. The DRS spectra showed that Z-Cu exhibited an intense absorption maximum at ~280 nm, which can be associated with the presence of Cu 2+ ions within the zeolite. The photocatalytic activity of Z-Cu was proved through comparative studies of photolysis, photocatalysis on Z-Na and photocatalysis on Z-Cu. |
