Photocatalytic activity of snow-like Bi2WO6 microcrystalline for decomposition of Rhodamine B under natural sunlight irradiation

Controllable synthesis and photocatalytic activity of spherical, flower-like and nanofibrous bismuth tungstates

“…All diffraction peaks can be assigned to the orthorhombic Bi 2 WO 6 (JCPDS no. 39-0256), which are consistent with the results reported by other researchers [6,12,30]. No peaks of impurities were detected from these patterns.…”

“…Bi 2 WO 6 is the simplest member of the Aurivillius family (when n = 1) with general formula Bi 2 A n−1 B n O 3n+3 (A = Ca, Sr, Ba, Pb, Bi, Na, K and B = Ti, Nb, Ta, Mo, W, Fe), which usually have the layer structures and unique properties [5,6,[12][13][14]. Recent years, Bi 2 WO 6 has attracted extensive attentions due to its excellent intrinsic physical and chemical properties such as ferroelectric piezoelectricity, catalytic behavior, and nonlinear dielectric susceptibility [15,16].…”

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

“…Thus, it shows great potential as a VLD photocatalyst [8][9][10][11][12][13][14]. However, on the account of its high electron-hole recombination rate in the process of photocatalytic reaction, its applications are still restricted.…”

Visible-light-driven photocatalysis of heterostructure Ag/Bi2WO6 nanocomposites and their photocatalytic degradation of dye under visible light irradiation

“…cations alternatively residing above and below, including the formation of BiO 4 square pyramids' caps [12][13][14]. They have very interesting physical properties: ferroelectricity, piezoelectricity, pyroelectricity, catalytic behavior, nonlinear dielectric susceptibility, visible-light-induced photocatalyst splitting water into H 2 and O 2 , and decomposition of organic contaminants [15][16][17]. Bi 2 WO 6 sample (2.80 eV) [18] has suitable valence band (VB) that meets the potential level of oxidizing organic contaminants under visible-light irradiation.…”
