Kaiqi Wang et al.

Summary: This work designed and prepared a novel heterojunction composite NiO/BaTiO3 through a method of photo-deposition and used it in piezocatalytic dye removal for the first time. The results showed that the NiO/BaTiO3 composite exhibited superior efficiency and stability in RhB degradation under ultrasonic wave vibration. The optimized NiO/BaTiO3 sample synthesized under light irradiation for 2 h demonstrated a RhB degradation rate of 2.41 h-1, which was 6.3 times faster than that of pure BaTiO3. By optimizing the piezocatalytic reaction conditions, the degradation rate constant of NiO/BaTiO3 can further reach 4.14 h-1.

Photocatalytic properties of BiOBr/BiOCl/AgBr ternary photocatalysts for degradation of RhB dye

Xiao-hua Zheng et al.

Summary: A series of BiOBr/BiOCl/AgBr ternary composite photocatalysts with excellent photocatalytic performance was synthesized by coprecipitation, and their catalytic degradation property of rhodamine B dye under visible light irradiation was investigated. The results showed that the BiOBr/BiOCl/AgBr nanocomposites with 20% molar fraction of AgBr (molar ratio of BiOBr/BiOCl =1:1) exhibited the best photocatalytic performance, with a rate 3.6 times that of BiOCl, 3.1 times that of BiOBr, and 55.9 times that of AgBr. The formation of S-scheme heterojunction effectively reduced the recombination of photoelectron-hole pairs, resulting in a significant improvement in the photocatalytic performance of the ternary composite catalyst.

Novel Bi2WO6/ZnSnO3 heterojunction for the ultrasonic-vibration-driven piezocatalytic degradation of RhB

Chunran Zhao et al.

Summary: This study designed and prepared a new piezoelectric catalytic nanomaterial, Bi2WO6/ZnSnO3, and applied it in piezocatalytic water purification. Results showed that the composite had superior piezocatalytic efficiency and stability in rhodamine B (RhB) degradation under ultrasonic vibration. The improved performance was attributed to the enhanced specific surface area, facilitated piezocatalytic reaction, and the formation of type-II heterojunction structures between Bi2WO6 and ZnSnO3, which improved the separation efficiency of charge carriers and greatly enhanced the piezoelectric catalytic activity.

A novel strategy for arsenic removal from acid wastewater via strong reduction processing

Zhi Feng et al.

Summary: In this paper, a simple and efficient method was proposed to reduce arsenic in high-acidic arsenic-containing wastewater, which poses significant threats to human health and ecological safety. By using potassium borohydride (KBH4) as a reducing agent, soluble arsenic was converted into gaseous arsine (AsH3) or solid arsenic (As-0) to remove arsenic from the wastewater. The reaction kinetics analysis showed that the fast reaction stage followed pseudo-first-order kinetics, with an arsenic removal rate of over 73% in 0.5 minutes and equilibrium reached after 30 minutes. Various influencing factors, including arsenic valence, aeration, addition method, concentrations of reducing agent, and hydrogen ion (H+) concentration, were investigated. The results demonstrated that As(III) was easier to be removed than As(V), multiple additions of KBH4 and aeration were favorable for arsenic removal, increased KBH4 concentration enhanced the removal of arsenic, appropriate H+ concentration contributed to arsenic removal while excessive H+ concentration had an inhibitory effect. The maximum removal rate of arsenic reached 95.87%, with a maximum removal capacity of 45.50 mg/g. XRD and SEM-EDS analysis confirmed that amorphous arsenic (As-0) was generated after reduction of soluble arsenic, with a mass ratio of more than 94.52%. The study also revealed the reaction mechanism of reductive degradation, where soluble arsenic reacts with hydrogen radicals (H center dot) to form solid arsenic (As-0) and gaseous arsine (AsH3) in a molar ratio of 6:1. While solid arsenic (As-0) is convenient for removal from wastewater, attention should be paid to the formation of AsH3 and strategies for AsH3 treatment should be considered.

Enhanced Selective Photooxidation of Toluene to Benzaldehyde over Co3O4-Modified BiOBr/AgBr S-Scheme Heterojunction

Jie Deng et al.

Summary: In this study, a Co3O4-modified BiOBr/AgBr heterojunction was successfully constructed for the photocatalytic selective oxidation of sp(3) C-H bonds at the benzylic position. The resulting benzaldehyde product exhibited a high selectivity, which was attributed to the unique S-scheme charge-transfer mode. The combination of AgBr's photogenerated electrons and O-2 generated O2- radicals, which effectively oxidized the benzyl radicals on the Co3O4 surface and thermodynamically decomposed into benzaldehyde.

Summary: BiOBr nanosheets and flower-like microspheres were prepared using hydrothermal and solvothermal methods, respectively, with the successful preparation of Bi/BiOBr nanosheets. The photocatalytic activity of the Bi/BiOBr catalyst was the highest, degrading norfloxacin in accordance with a first-order kinetic model. The increased activity of the Bi/BiOBr photocatalyst is attributed to the formation of a heterojunction that effectively inhibits the recombination of holes and photogenerated electrons.

Summary: A novel sulfurization protocol in pure carbon disulfide was used to establish Bi2S3-Bi2O3 binary composites at room temperature, with the in-situ produced Bi2S3 forming nanocrystals on the Bi2O3 surface to generate heterojunction structures.
