High Tribocatalytic Performance of FeOOH Nanorods for Degrading Organic Dyes and Antibiotics

Small Methods, Год журнала: 2024, Номер unknown

Опубликована: Фев. 28, 2024

Abstract Tribocatalysis is vitally important for electrochemistry, energy conservation, and water treatment. Exploring eco‐friendly low‐cost tribocatalysts with high performance crucial practical applications. Here, the highly efficient tribocatalytic of FeOOH nanorods reported. The factors related to activity such as nanorod diameter, surface area, roughness are investigated, diameter found have a significant effect on their performance. As result, under ultrasonic excitation, optimized exhibit superior degradation toward rhodamine B (RhB), acid orange 7, methylene blue, methyl dyes, mixture. RhB mixed dyes effectively degraded within 20 min ( k = 0.179 −1 ) 35 0.089 ), respectively, showing excellent reusability. Moreover, antibiotics, tetracycline hydrochloride, phenol, bisphenol A efficiently degraded. Investigation catalytic mechanism reveals that friction‐generated h + well these yielded •OH •O 2 − active radicals participate in reaction. This work not only shed light design high‐performance tribocatalyst but also demonstrates by harvesting mechanical energy, promising materials removing organic contaminants wastewater.

Developing green, efficient, and sustainable techniques to synthesize hydrogen peroxide has always been the challenge faced by researchers. The rising-star piezocatalysis demonstrated be capable of drive redox reactions based on piezoelectric effect therefore may provide novel solutions for H2O2 production through mechanical energy conversion. Herein, bismuth layered compound Bi3TiNbO9 (BTNO) was utilized produce harvesting ultrasound vibration in a pure water system first time. A yield rate 407.05 μmol·g–1·h–1 achieved under ultrasonic conditions (40 kHz, 50 W) without any cocatalysts scavengers, surpassing majority reported piezocatalysts with similar mechanisms. Furthermore, satisfied circulation long-term running stability piezocatalyst BTNO were proved, accumulated concentration could reach 1127 μM after 5 h reaction. response piezoresponse force microscopy (PFM), electrochemical characterization, piezodeposition experiments. On basis band structure analysis, possible pathway generating proposed according radical-trapping atmosphere control experiment results. It found that both oxidation reaction (WOR) oxygen reduction (ORR) contributed H2O2, but direct WOR plays an absolute dominant role. In addition, Ar sparging verified able efficiently enhance generation due enlarged cavitation effect, superior its photocatalysis synthesizing H2O2. is hoped this work can deep insights into offer clues synthesis peroxide.
