Sonocatalysis has attracted excellent research attention to eradicate hazardous pollutants from the environment effectively. This work synthesised an organic/inorganic hybrid composite catalyst by coupling Fe3O4@MIL-100(Fe) (FM) with ZnS nanoparticles using solvothermal evaporation method. Remarkably, material delivered significantly enhanced sonocatalytic efficiency for removing tetracycline (TC) antibiotics in presence of H2O2 compared bare nanoparticles. By adjusting different parameters such as TC concentration, dosage and amount, optimized (20 %Fe3O4@MIL-100(Fe)/ZnS) removed 78.25% antibiotic 20 min at cost 1 mL H2O2. These much superior activities are attributed efficient interface contact, effective charge transfer, accelerated transport capabilities strong redox potential acoustic catalytic performance FM/ZnS systems. Based on various characterization, free radical capture experiments energy band structures, we proposed a mechanism degradation based S-scheme heterojunctions Fenton like reactions. will provide important reference developing ZnS-based nanomaterials study sonodegradation pollutants.

Organic dyes play vital roles in the textile industry, while discharge of organic dye wastewater production and utilization has caused significant damage to aquatic ecosystem. This review aims summarize mechanisms photocatalysis, sonocatalysis, sonophotocatalysis treatment recent advances catalyst development, with a focus on synergistic effect ultrasound light catalytic degradation dyes. The performance TiO2-based catalysts for photocatalytic, sonocatalytic, sonophotocatalytic systems is compared. With light, generally performs much better than sonocatalysis or photocatalysis alone pollutant degradation, yet it higher energy requirement. Future research directions are proposed expand fundamental knowledge process enhance its practical application degrading wastewater.

Facile synthesis of BiOI/BaNbO3 composite for rapid sonocatalytic degradation of tetracycline hydrochloride

Journal of Solid State Chemistry, Journal Year: 2024, Volume and Issue: 333, P. 124644 - 124644

Published: Feb. 27, 2024

Sonocatalysis, a vibration-induced chemical reaction, has shown great potential for catalytic applications. This study used water bath method to prepare BiOI/BaNbO3 composites with various mass ratios. Under the influence of sonocatalysis, BI/B-0.5 catalyst could degrade tetracycline hydrochloride up 96.5 % after 20 min, and stability was good. In comparison pure BiOI BaNbO3, reaction rate constants were found be 7.2 13.7 times higher, respectively. Furthermore, we systematically investigated sonocatalytic degradation effect on HTC under conditions. Finally, propose possible mechanism by composite catalyst. Our results underscore superior efficiency achieved catalyst, demonstrating its efficient removal organic pollutants.
