Controlled synthesis of hierarchical Bi2WO6 microspheres with improved visible-light-driven photocatalytic activity

Ethylene glycol-assisted solvothermal fabrication of ZnWO4 nanostructures with tunable size, optical properties, and photocatalytic activities

“…Chen et al [41] found that the capped EG molecules on the surface of Bi 2 WO 6 microsphere lowed down the photocatalytic activity of the sample, here the same conclusion can be done that the more remaining unwashed EG molecules on surface of small ZnWO 4 nanocrystals fabricated with large amount of EG(28 ml) and only a few water(2 ml) compared to other ZnWO 4 nanorods obtained with much less volume ratio of EG and water lead to decreased photocatalytic performance.…”

Highly efficient photocatalytic oxidation of phenol over ordered mesoporous Bi2WO6

“…It has attracted extensive attention in many research fields due to its excellent intrinsic physical and chemical properties [14][15][16], such as ferroelectric piezoelectricity, pyroelectricity, catalytic activity, and a non-linear dielectric susceptibility [17]. Especially, the visible-light-driven photocatalytic activity of Bi 2 WO 6 has been widely studied [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. Kudo et al found that Bi 2 WO 6 had visible-light-induced photocatalytic activity for O 2 evolution from water [18].…”

Study of the sulfurized (BiO)2CO3 as efficient visible-light induced photocatalyst

“…A large number of semiconductor materials as photocatalyst have been developed, such as TiO 2 [2,3], ZnO [4][5][6][7], WO 3 [8,9], BiVO 4 [10][11][12], Bi 2 WO 6 [13,14] and BiOX [15][16][17][18][19][20][21]. However, the low photocatalytic efficiency and unfavorable chemical stability still hinders their practical application in elimination of the environmental hazardous contaminants.…”
