Enhanced visible-light photocatalytic activity of Fe/ZnO for rhodamine B degradation and its photogenerated charge transfer properties

Sensitivity analysis of the photoactivity of Cu–TiO2/ZnO during advanced oxidation reaction by Adaptive Neuro-Fuzzy Selection Technique

“…Moreover, metal ions affect the charge carrier equilibrium concentration by serving as electron/hole trap and increase the degradation rate. As reported by Yi et al [5], metal species increase the electron capture capacity of semiconductors. In Yi's work [5], iron doped zinc oxide nanoflowers were synthesized via a simple hydrothermal process.…”

Effect of the interface on UV–vis–IR photodetection performance of PbS/ZnO nanocomposite photocatalysts

“…For example, Choi et al reported that tailoring the PbS/metal interface by the simple oxidation of PbS QDs greatly improved photovoltaic performance [28]. On the other hand, ZnO as wide bandgap semiconductor (3.37 eV) has been extensively investigated for many applications such as UV photodetection, photocatalytic purification [29][30][31][32][33][34][35]. The conduction band edge and valence band edge of ZnO are lower than the corresponding that of narrow band PbS.…”

Direct in situ activation of Ag0 nanoparticles in synthesis of Ag/TiO2 and its photoactivity

“…However, these methods experience a few weaknesses such as generating secondary products and producing large amounts of sludge, in addition to being costly and time consuming [7][8][9]. Advanced oxidation processes (AOPs), which usually use a heterogeneous photocatalyst semiconductor, have become a popular method for the removal of this recalcitrant pollutant [10][11][12].…”
