Název v původním jazyce
Enhancement of photocatalytic properties of Co+2:ZnO nanowires by applied magnetic field
Popis výsledku v původním jazyce
The photocatalytic performance of the bare ZnO NWs and Co2+: ZnO NWs is evaluated with respect to the degradation rate of the MB solution under the UV light irradiation. The percent of MB degradation increases gradually with the increase of radiation time. The photocatalytic properties of bare ZnO NWs do not show a clear difference without and with magnetic field H= 0.2 T. Interestingly, Co+2 / ZnO NWs could show 25% enhancement of photocatalytic degradation with applied magnetic field. This mechanism could be related to magnetic absorption (MA) effect. The absorption spectra of the Co+2 / ZnO NWs measured with and without a magnetic field are clearly separated after the onset of the absorption (~3.4 eV). The absorption change is positive while the applied magnetic- field and becomes significant after the onset of the absorption. However, no obvious MA effect has been observed for the ZnO NWs.
