Název v původním jazyce

Enhanced photodegradation in metal oxide nanowires with Co-doped surfaces under a low magnetic field

Popis výsledku v původním jazyce

The enhancement of photodegradation in the Co rich-doping of ZnO nanowire surfaces (Co2+/ZnO NWs) prepared with a combination method of Co sputtering on ZnO NWs and post immersion in deionized water, the latter of which exploits the nature of the hydrophilic–hydrophobic transitions at the ZnO surfaces as a result of the diffusion of Co atoms. Due to the controllable spin-dependent density of states (DOS) induced by the Co2+, the photodegradation of methylene blue dye can be further boosted by approximately 90% through the use of a conventional permanent magnet with a relatively low magnetic field strength of approximately 0.15 T. The reliability of the spin polarization–modulation scheme by means of surface doping, as experimentally evidenced by the magnetic response in the X-ray absorption measurements and magnetic circular dichroism, offers the opportunity to create highly efficient catalysts by engineering surfaces based on tailoring their spin-dependent DOS.
