Buoyancy-Assisted Fabrication of Liquid Diode: Janus Nanofibrous Membrane for Efficient Wastewater Treatment

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(32), С. 42641 - 42659

Опубликована: Авг. 1, 2024

The pressing need for effective methods to separate oil and water in oily wastewater has spurred the development of innovative solutions. This work presents creation evaluation a Janus nanofibrous membrane, also known as Liquid Diode, developed using electrospinning (e-spinning) buoyancy-assisted hydrothermal techniques. membrane features unique structure: one side is composed PVDF nanofibers embedded with GO/TiO2 composite, exhibiting in-air superhydrophobic superoleophilic properties, while reverse consists ZnO nanorod array, demonstrating superhydrophilic underwater (UW) superoleophobic properties. distinct asymmetric wettability enables effectively both water-in-oil (w-in-o) oil-in-water (o-in-w) emulsions, achieving an impressive liquid flux separation efficiency (SEff). achieves maximum (Fo) 3506 ± 250 L m–2 h–1, (Fw) 1837 150 SEff exceeding 98% sides. Furthermore, maintained reliable mechanical stability after 10 cycles sandpaper abrasion test demonstrated excellent chemical when subjected acidic, alkaline, cold hot conditions 24 h. These combined its ability breaking down organic contaminants (98% 2% 210 min) pharmaceutical (97% under visible light, highlight photocatalytic potential. Additionally, membrane's antifouling antibacterial properties suggest long-term sustainable use treatment applications. synergistic combination these superior positions promising solution addressing complex challenges environmental remediation.

Superhydrophobic-Activated Carbon Coating: A Path toward Demulsification and Separation of Crude Oil Emulsions

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Май 15, 2025

The emissions of oily wastewater represent a considerable risk to the environment. demulsification and separation crude oil emulsions have been difficult problems in field petroleum. Consequently, development green, cost-effective, highly efficient and/or oil-water technologies has emerged as critical research priority. In this study, activated carbon (AC) was designed be modified by using hexadecyltrimethoxysilane (HDTMS) superhydrophobic material. By spraying mixture AC epoxy resin onto 300# 2000# stainless steel mesh (SSW), AC-coated SSWs with excellent wetting resistance durability were developed. These completely replaced demulsifiers for achieving emulsions. SSW demonstrated remarkable efficiency above 96.6% across five types mixtures. For chloroform-water mixtures, flux consistently remained 97.7% 12050 L·m-2·h-1 over 20 consecutive cycles. also stable 94.8% 490.8 water-in-chlorobenzene (W/O) after This underscores material's consistent high performance oil/water processes. strategy materials may provide general hydrophilic modification method new generation high-performance coatings offers prospective technical support rapid purification wastewater.

Hollow Porous Organic Nanosphere-Supported ZnO Composites for Photodegradation of Crystal Violet

Catalysts, Год журнала: 2025, Номер 15(6), С. 529 - 529

Опубликована: Май 27, 2025

In this work, we have reported a simple synthesis method for hollow porous organic nanosphere-supported ZnO composite photocatalyst (HPON@ZnO) through combination of hyper-crosslinking-mediated self-assembly and “ship-in-bottle” strategy. The obtained HPON@ZnO possesses large specific surface area hierarchically structures, which exhibited exceptionally high catalytic activity in the adsorption degradation crystal violet, with reaction proceeding under mild conditions. Additionally, catalyst demonstrated towards other dyes featured good stability recyclability. This strategy provides new approach large-scale efficient heterogeneous photocatalysts, offers an effective dye wastewater treatment technique.
