BiOBr hybrids for organic pollutant removal by the combined treatments of adsorption and photocatalysis

Abstract

The xSiO2–BiOBr (x = 0–5) and SN–SiO2–BiOBr hybrids were synthesized via a facile one step co-precipitation method.

Selective synthesis of visible light active γ-bismuth molybdate nanoparticles for efficient photocatalytic degradation of methylene blue, reduction of 4-nitrophenol, and antimicrobial activity

“…The nal products of the photocatalytic degradation of MB result in the formation of CO 2 , H 2 O, and others. 38,39 The formation of cOH radical was probed by photoluminescence (PL) spectroscopy. 36 Fig.…”

Room temperature synthesis of BiOBr1−xIx thin films with tunable structure and conductivity type for enhanced photoelectric performance

“…12 BiOBr and BiOI can respond to visible light, indicating the efficient conversion of solar energy, but BiOI exhibits a faster photocarrier recombination rate than BiOBr. 13 To improve the BiOBr visible light absorption, some strategies have been applied, including controlling the synthesis of BiOBr with specic morphology and structure, 14,15 constructing BiOBr-based composites with other semiconductors, [16][17][18] doping with metal atoms and so on. 19,20 In addition, within ion doping, selfdoping of halogens (Cl, Br, I) is an effective method to strengthen the visible light utilization and overcome the drawback of the high recombination rate of electron-hole pairs.…”

Novel 2D/2D BiOBr/UMOFNs direct Z-scheme photocatalyst for efficient phenol degradation

“…In the past few decades, the development of high-efficiency visible-light-driven photocatalysts has received extensive attention in the photocatalysis field [12][13][14][15][16][17]. Among reported visible-lightdriven photocatalysts, BiOBr has attracted significant attention due to its convenient tunability by halogen elements, photochemical stability, and a lamellar structure for decomposing various organic pollutants in water [18][19][20][21][22][23]. For instance, Huo et al assembled hierarchical flower-like BiOBr microspheres via a solvothermal method [24].…”
