Facile fabrication of the visible-light-driven Bi₂WO₆/BiOBr composite with enhanced photocatalytic activity

Preparation of flower-like BiOBr–WO 3 –Bi 2 WO 6 ternary hybrid with enhanced visible-light photocatalytic activity

“…Recently, many binary Bi 2 WO 6 -based composites have been studied, such as BiOBr [15][16], Bi 2 O 2 CO 3 [17], CdS [18], Co 3 O 4 [19], WO 3 [20], ZnFe 2 O 4 [21] and so on. Among these, WO 3 is a good candidate as the conduction band (CB) position (0.74 eV vs NHE) [22] of WO 3 lies lower than that of Bi 2 WO 6 (0.24 eV vs NHE) [23].…”

Facile fabrication of In2O3/Bi2WO6 heterostructured microbelts with enhanced photocatalytic activity

“…3a, b that all the diffraction peaks of the samples were readily indexed to the pure orthorhombic Bi 2 WO 6 phase (JCPDS No. 39-0256) [35] and cubic In 2 O 3 (JCPDS No. 06-0416) [27].…”

The highly enhanced visible light photocatalytic degradation of gaseous o -dichlorobenzene through fabricating like-flowers BiPO 4 /BiOBr p-n heterojunction composites

“…On the other hand, p-n heterojunction, which can be as an efficient and promising method for enhancing the photocatalytic activity of BiOBr, can extend the probability of photo-induced electron-hole separation via an additional internal electric field [27,[34][35][36]. Up to now, some p-n heterojunction photocatalysts have been developed, for example BiOBr nanosheets@TiO 2 nanobelts [37], BiOBr/CoFe 2 O 4 [9] and Bi 2 WO 6 /BiOBr [38]. The results indicate that these p-n junction photocatalysts display much higher photocatalytic activity than the individual compound.…”
