Summary: BiOBr/FeWO4 nanomaterials with S-scheme heterojunction were synthesized and used for sonocatalytic degradation of Tetracycline (TC) in the presence of K2S2O8. The optimized experimental conditions resulted in the removal of 86.54 +/- 4.26% TC using BiOBr/FeWO4 sonocatalyst. Addition of K2S2O8 enhanced the sonocatalytic performance, achieving a removal ratio of 92.99 +/- 0.24% within 30 minutes. The sonocatalyst demonstrated excellent reusability and stability. The mechanism of TC degradation and possible degradation intermediates were proposed. The synthesized BiOBr/FeWO4 sonocatalyst showed great potential for the removal of organic pollutants by sonocatalysis.

Summary: This study presents a facile and cost-effective method to synthesize a stable photocatalyst (BiOBr/MMT) for sulfite activation under sunlight. The BiOBr/MMT catalyst demonstrates enhanced catalytic performance in degrading atrazine and various organic pollutants. The addition of MMT reduces the bandgap and increases the surface area of pristine BiOBr, leading to improved adsorption capability. The BiOBr/MMT-sulfite system generates oxysulfur radicals, h(+), and O-1(2) as the dominant active species. The proposed degradation mechanism highlights the vital role of sulfite adsorption on the surface of the photocatalyst.

Summary: The oxygen-vacancy-rich BiOBr shows higher photocatalytic activity than the oxygen-vacancy-deficient counterpart. This study reveals that the strong adsorption and rapid degradation of the cyanotoxin cylindrospermopsin (CYN) on oxygen-vacancy-rich BiOBr is attributed to the strong interaction between the highly hydrophilic sulfate group of CYN and oxygen-vacancy sites. The formation of Brönsted acid sites (OHB) on OV sites enhances the adsorption of the sulfate group.

Summary: This study demonstrates that surface phosphorylation can greatly enhance the O2 photoactivation of BiOBr, leading to a higher generation rate of superoxide radicals. The phosphorylated BiOBr surface establishes an interfacial electrostatic field, weakens the surface Bi-O bonds, and induces oxygen vacancy (VO) generation, facilitating exciton dissociation and the activation of absorbed O2. This surface phosphorylated BiOBr shows a significantly higher degradation rate of chlorobenzene solution and is able to decrease the COD value of industrial chlorobenzene wastewater below the water quality standards.
