Preparation of sputter-deposited Cu-doped BiVO4 nanoporous thin films comprised of amorphous/crystalline heterostructure as enhanced visible-light photocatalyst

“FeV-cofactor”-inspired bionic Fe-doped BiVO4photocatalyst decorated with few-layer 2D black phosphorus for efficient nitrogen reduction

“…4b shows the XPS spectra of V 2p, which contains two peaks with binding energies of 524.4 and 516.9 eV, respectively, ascribed to V 2p 1/2 and V 2p 3/2 of the V 5+ cation. After Fe ion doping, a new peak at 515.0 eV can be assigned to the V 4+ cation, 42 which confirms the formation of a couple of oxygen vacancies and V 4+ species in Fe-doped BiVO 4 . Furthermore, the XPS spectra of Bi are shifted by doping Fe ions, demonstrating that Fe is involved in the bonding of the BiVO 4 lattice 43 (Fig.…”

Investigation doping effects of Copper to enhance photocatalytic performance of Tungsten Trioxide for advanced Tetracycline elimination even under visible light

“…The interference of Cu dopants, which replaced numerous W elements in the WO 3 lattice, could be the cause of the divergence. The replacement caused the lattice disorder because Cu 2+ and W 6+ have different ionic radii (Assadi &Hanaor 2016, Bakhtiarnia et al 2023, Khalid et al 2022, Naeimi et al 2022). Hence, the acquired XRD pattern outcomes designated that Cu was effectively doped into the crystal structure of WO 3 .…”
