Bi2WO6/Cu0: A novel coupled system with enhanced photocatalytic activity by Fenton-like synergistic effect

Hydrothermal Synthesis of Iodine-Doped Nanoplates with Enhanced Visible and Ultraviolet-Induced Photocatalytic Activities

“…The microstructure of the iodine-doped Bi 2 WO 6 sample was investigated by TEM. Figure 3 27 27.5 28 28. with the diameter of 50-100 nm. An HRTEM image of I-BWO is shown in Figure 3 To further confirm the composition of the iodine-doped Bi 2 WO 6 , the energy dispersive spectrum was measured to analyze the elements and contents of the as-prepared I-BWO.…”

“…Therefore, it is necessary to take some measures to improve the migration efficiency of photoinduced electrons and suppress the recombination of photoinduced electrons and holes effectively. Recently, the modification of Bi 2 WO 6 with Cu nanoparticles [27] exhibited a Fenton-like synergistic effect on improving the visible-light induced photocatalytic activity. Besides, Ag nanoparticles [28], C [29,30], TiO 2 [31][32][33], PtCl 4 [34], Bi 2 O 3 [35], Ag 2 O [36], and ZnWO 4 [37] were also used to modify the Bi 2 WO 6 catalyst, which can inhibit the recombination of photoinduced electrons and holes effectively and improve the photocatalytic performance greatly.…”

Novel Y doped Bi2WO6 photocatalyst: Hydrothermal fabrication, characterization and enhanced visible-light-driven photocatalytic activity for Rhodamine B degradation and photocurrent generation

“…In order to resolve this problem, the route of ion doping by incorporation of a certain amount of metal or nonmental elements into Bi 2 WO 6 is employed to depress the recombination of free carriers and improve the migration efficiency of photogenerated electrons and holes. Till now, doping by metal or nonmental elements, such as Fe [15], Cu [16], Ag [17], F [18] and N [19] etc in Bi 2 WO 6 has been proven to be effective in the enhancement of the photocatalytic activities. Lately, our…”

ZnWO4–Cu system with enhanced photocatalytic activity by photo-Fenton-like synergistic reaction

“…3b. The peaks at the binding energies of 952 eV and 932 eV could be assigned to Cu 0 2p 1/2 and Cu 0 2p 3/2 respectively [19]. The peaks of Zn 2p orbital were located at 1023 eV and 1046 eV (Fig.…”
