2D/2D Bi₂WO₆/Protonated g-C₃N₄ step-scheme heterojunctions for enhancing the photodegradation of 17β-estradiol: promotional role of electrostatic interaction

Abstract

17β-Estradiol (E2) is a type of endocrine disrupting chemicals (EDCs) with the strongest estrogenic activity which poses a huge threat to the ecosystems and human health even at extremely low...

Construction of 2D S‐Scheme Heterojunction Photocatalyst

“…For example, using Bi(NO 3 ) 3 as the Bi source, a series of 2D S-scheme photocatalysts composed of g-C 3 N 4 and Bibased photocatalysts is prepared by in situ growth method, such as 0D/2D Bi 4 V 2 O 11 /g-C 3 N 4 , [31] 1D/2D Bi 2 S 3 /g-C 3 N 4 , [32] 2D/2D BiOBr/g-C 3 N 4 , [33] and 2D/2D Bi 2 WO 6 /g-C 3 N 4 composites. [34] Apart from Bi-based compounds, some metal oxides such as W 18 O 49 nanorods, [35] TiO 2 nanosheets (NS), [36] and Fe 2 O 3 nanosheets, [37] are in situ deposited on the surface of g-C 3 N 4 nanosheets utilizing the hydrolysis of metal ions.…”

Photocatalytic degradation of rhodamine-B by visible light assisted peroxymonosulfate activation using the Z-scheme MIL-100(Fe)/Bi2S3 composite: a combined experimental and theoretical approach

“…7,8 In this regard, development of visible light responsive photocatalytic composites can be an attractive alternative to eliminate the high energy demand. Different types of semiconductor materials and composites, like composite metal oxides, 9–13 metal carbides, 14,15 metal sulfides, 8,16 graphene derivatives, 17 graphitic carbon nitride, 18–21 metal organic frameworks (MOFs), 22–24 MXene, 25 etc. , have been employed as highly effective photocatalysts in the removal of various contaminants in water.…”

“…7,8 In this regard, development of visible light responsive photocatalytic composites can be an attractive alternative to eliminate the high energy demand. Different types of semiconductor materials and composites, like composite metal oxides, [9][10][11][12][13] metal carbides, 14,15 metal sulfides, 8,16 graphene derivatives, 17 graphitic carbon nitride, [18][19][20][21] metal organic frameworks (MOFs), [22][23][24] MXene, 25 etc., have been employed as highly effective photocatalysts in the removal of various contaminants in water. To increase the harvesting of visible light irradiation, lowering the excited e À /h + recombination, as well as introducing more reactive sites for photocatalytic reactions, formation of heterojunctions between different visible light responsive semiconductors is a viable option.…”
