All-solid-state Z-scheme ZnFe-LDH/rGO/g-CN heterojunction for enhanced sonophotocatalytic degradation of ciprofloxacin: Performance and mechanistic insights.

The fabrication of all-solid-state Z-scheme sonophotocatalysts is vital for improving the transfer rate of photogenerated electrons to remove antibiotics present in wastewater. Herein, a novel indirect Z-scheme ZnFe-layered double hydroxide (LDH)/reduced graphene oxide (rGO)/graphitic carbon nitride (g-CN) heterojunction was synthesized using a simple strategy. The ZnFe-LDH/rGO/g-CN (ZF@rGCN) ternary composites were systematically characterized using different techniques.

Enhanced catalytic oxidation of naproxen via activation of peroxymonosulfate by Fe-based metal-organic framework aerogels functionalized with Ag nanoparticles.

In this study, AgPO and Fe-based metal-organic frameworks (MOFs)-functionalized three-dimensional (3D) porous gelatin aerogels (Ag/Fe@GMA) were fabricated and used as adsorbents and catalysts for the activation of peroxymonosulfate (PMS) for naproxen (NPX) removal from water. The morphology, crystallinity, surface functional groups, and surface chemical element compositions of the fabricated Ag/Fe@GMA was evaluated using various analytical techniques. Our results showed that as an adsorbent, Ag/Fe@GMA showed a 18.

Adsorptive and photocatalytic performance of cobalt-doped ZnTiO/TiCT MXene nanohybrids towards tetracycline: Kinetics and mechanistic insight.

Tetracycline (TC) antibiotics are widely used in animal husbandry and can cause environmental risk due to its high ecological toxicity and persistence. In this study, cobalt doped/ZnTiO (ZTO)/TiCT MXene (ZCxTM, x indicates wt% of Co loading) was synthesized and explored to remove TC by adsorption and photocatalysis under visible light irradiation. The as-prepared ZC5TM was characterized using various analytical techniques, and key operating parameters such as solution pH, background ions, and temperature were systematically investigated.

Synthesis, performance, and mechanisms of strontium ferrite-incorporated zeolite imidazole framework (ZIF-8) for the simultaneous removal of Pb(II) and tetracycline.

In this study, strontium ferrite (SF)-incorporated zeolite imidazole framework (ZIF-8) (SFZIF-8) that can simultaneously uptake Pb(II) and tetracycline (TC) in solution was synthesized and characterized. The physicochemical properties of the as-prepared SFZIF-8 were characterized by various functional groups, higher average pore diameter (3.414 nm), and stronger negative charge (-30.
