Monolayered Bi2WO6 nanosheets mimicking heterojunction interface with open surfaces for photocatalysis

Abstract: Two-dimensional-layered heterojunctions have attracted extensive interest recently due to their exciting behaviours in electronic/optoelectronic devices as well as solar energy conversion systems. However, layered heterojunction materials, especially those made by stacking different monolayers together by strong chemical bonds rather than by weak van der Waal interactions, are still challenging to fabricate. Here the monolayer Bi2WO6 with a sandwich substructure of [BiO]+–[WO4]2−–[BiO]+ is reported. This mater… Show more

“…[1][2][3][4][5] In photocatalysis area, 2D monolayer photocatalysts, have shown huge advantage in promoting the photocatalytic activity, which is mainly reflected in the following aspects: first of all, 2D monolayer maximizes the surface area for sufficient reactive sites. [6][7][8][9] Secondly, 2D monolayer morphology minimizes the distance for photo-generated electrons/holes transport to the reaction interface.…”

“…Herein, isopropyl alcohol (IPA), benzoquinone (BQ), and ethylenediaminetetraacetic acid (EDTA) were introduced into the degradation process to attempt to trap cOH, O 2 c À , and h + , respectively. [37][38][39][40][41] As shown in Fig. 5(f), there was no signicant effect on the degradation rate when IPA was added, thus suggesting that cOH is not a dominant active species in the degradation process.…”

“…The oxyhalide main focused on bismuth oxyhalides with adjustable halogen types and oxygen/halogen ratio, such as BiOCl, BiOBr, BiOI, Bi 12 O 17 Cl 2 , Bi 3 O 4 Br, Bi 4 O 5 Br 2 , and so on 26, 27, 28, 29, 30, 31. The oxometallate mainly includes Ca 2 Nb 3 O 10 , Ba 5 Nb 4 O 15 , SnNb 2 O 6 , K 4 Nb 6 O 17 , SrNb 2 O 6 , HNbWO 6 , Bi 2 WO 6 , Bi 2 MoO 6 , and BiVO 4 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43. The hydroxides can be classified as single metal hydroxides (e.g., Ni(OH) 2 ) and layered double hydroxides (LDHs) including CoCo LDHs, NiCo LDHs, NiFe LDHs, Ni 0.75 V 0.25 LDHs, CoMn LDHs, CoFe LDHs, NiCoFe LDHs, ZnAl LDHs, CuCr LDHs, and MgAl LDHs 44, 45, 46, 47, 48, 49, 50, 51, 52, 53.…”
