AgI/CuWO4 Z-scheme photocatalyst for the degradation of organic pollutants: Experimental and molecular dynamics studies

Optimizing the synergistic effect of CuWO4/CuS hybrid composites for photocatalytic inactivation of pathogenic bacteria

“…9. The E cb and E vb values of CuWO 4 and CuS were estimated using the following expressions: 62 E vb = χ − E 0 + 0.5 E g E cb = E vb − E g where E vb is the valence band (VB) edge potential, the E 0 value is constant 4.5 eV versus a normal hydrogen electrode (NHE), E cb is the conduction band (CB) edge potential, E g is the bandgap of the semiconductor, and χ is the geometric mean of the electronegativities of atoms constituting the semiconductor. The VB position and CB position are estimated to be +2.9 eV and 0.50 eV, respectively for CuWO 4 , 63,64 whereas these values are +1.67 eV and −0.13 eV respectively for CuS.…”

Cd-doped Ag2O/BiVO4 visible light Z-scheme photocatalyst for efficient ciprofloxacin degradation

“…The XRD of all composite samples showed the presence of both Ag 2 O and BiVO 4 phases, indicating nanocomposite formation. 30 Hereafter, the investigation concentrates on D1/10V sample characterization because of its enhanced photocatalytic activity (compared to D1/5V and D1/20V composites) towards CIP. Fig.…”

“…The major peaks in the XRD at 18.9°, 29°, 30.7°, 42.5°, and 53.4°are indexed to the (011), (112), (004), (015), and (116) planes of the body-centered monoclinic BiVO 4 . The XRD of all composite samples showed the presence of both Ag 2 O and BiVO 4 phases, indicating nanocomposite formation 30. Hereaer, the investigation concentrates on D1/10V sample characterization because of its enhanced photocatalytic activity (compared to D1/5V and D1/20V composites) towards CIP.…”

Visible‐Light Photocatalytic and Photo‐bactericidal Activity of Ni‐CuWO4/OTiO2 Composite†

“…[ 37 ] To avoid this situation, herein, we rationally designed a simple and non‐doping method to synthesize the oxygen‐rich TiO 2 lattice (namely O‐TiO 2 ), which can not only improve the photocatalytic activity and stability of the samples, but also depress the formation of the secondary phases, [ 38 ] shorten the energy band gap and reduce the carrier recombination efficiency.
