摘要: A novel nanocomposite electrode with tight and vertically aligned Zn0.5Mg0.5Fe2O4@TiO2 nanotube arrays (NTs) has been successfully synthesized via an ultrasonically assisted electrodeposition strategy. The scanning electron microscopy (SEM), transmission (TEM) X-ray diffraction (XRD) of the composite nanostructures indicated that as-prepared electrodes were well-aligned TiO2 NTs Zn0.5Mg0.5Fe2O4 nanoparticles. enhanced absorption under simulated sun light visible regions observed. photoelectrochemical performance showed excellent sensitive response to light. surface-interface charge separation transfer photo-induced electrons holes also demonstrated by optical characterization. Meanwhile, investigations clearly illustrated had more effective photo-conversion capability than unloaded NTs. saturated photocurrent density doped was about 6.5 fold 4 as high illumination light, respectively. In addition, photoelectrocatalytic (PEC) ability in degradation toxic p-nitrophenol species. much improved PEC activity can be attributed both visible-light photocatalytic heterostructure between TiO2.
