Exploring efficient heterogeneous photo-Fenton catalysis is crucial for advanced water purification In this study, a series of multivariate (MTV) metal-organic framework MIL-100 (Sc 0.98, 0.95, 0.87, 0.75, 0.58, Fe 0.02, 0.05, 0.13, 0.250.42) catalysts with increasing Fe contents were synthesized to effectively degrade micropollutants. By incorporating the Fe-O cluster into the framework, the degradation rate of sulfamethylthiazole (SMX) was improved 11.85 times over the MTV MIL-100 (Sc 0.58, Fe 0.42). The permanent porous structures and high surface areas (1597 m2/g ∼ 1389 m2/g) facilitated the adsorption processes. Results show that the initial adsorption rates for quinolone and anti-inflammatory groups were extremely high, with v0 = 463.16 ∼ 407.15μg/g min. The modified material enhanced the visible-light absorption and facilitated the formation of reactive oxygen species (·OH, 1O2, and O2·-) under the irradiation of solar light. ESR trapping technologies and quenching experiments were applied. The pathway for ROS formation under solar-light irradiation was proposed in detail. Aromatic intermediates were identified and quant. analyzed using UPLC-Q-TOF-MS. We believe that this strategy of incorporating mixed metal clusters in MOFs offers useful guidance to improve the performance of current materials. This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Reference of 70458-96-7).
1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. Piperazine was first introduced as an anthelmintic in 1953. Piperazine compounds mediate their anthelmintic action by generally paralyzing parasites, allowing the host body to easily remove or expel the invading organism. Piperazine is formed as a co-product in the ammoniation of 1,2-dichloroethane or ethanolamine. These are the only routes to the chemical used commercially.Reference of 70458-96-7
