Bifunctional NiAlFe LDH-coated membrane for oil-in-water emulsion separation and photocatalytic degradation of antibiotic

Simple Method for the Fabrication of Multiple Superwetting Surfaces with Photoresponse

“…In order to achieve the separation of heavy oil–water mixtures or water-in-oil emulsions, the materials are usually SHB/SOL. The materials used for separation of light oil–water mixtures or oil-in-water emulsions are usually SHL/SOB. − In addition, there are some other superwetting materials that can realize the on-demand separation of oil–water mixtures or oil–water emulsions, such as superamphophobic, superamphiphilic, and smart-response materials, etc. The pore size is another important factor to consider.…”

Thermosensitive Microfibril Cellulose/MnO2 Membrane: Dual Network Structure, Photothermal Smart Modulation for Switchable Emulsion Separation

“…9,25 To date, researchers have developed single-layer wettability-switchable emulsion separation membranes that are thermosensitive, 26,27 pH-responsive, 28−30 and photoresponsive. 31,32 Zhang et al 26 prepared thermoresponsive poly(N-isopropylacrylamide)modified nylon membranes by the hydrothermal method, which could separate at least 16 types of emulsions. Using onestep in situ polymerization of polyaniline monomers in aqueous media, Li et al 28 developed a smart coating with pH-switchable wettability on a variety of general substrates such as polyester mesh, cotton, and sponge, enabling adjustable oil/water separation.…”

Zong et al 32 prepared a novel NiAlFe-layered double hydroxide/polydopamine/polyvinylidene fluoride (NiAlFeLDH/PDA/PVDF) membrane, which not only achieved emulsion separation but also showed good photocatalytic activity. From a scientific point of view, the developed membrane materials are limited, the membrane fabrication process is relatively complicated, and their cycling stability cannot be guaranteed.…”

“…This greatly limits the development of Janus membranes. Single-layer wettability-switchable emulsion separation membranes are gradually taking the lead in the field of emulsion separation because of their structural integrity, less material and energy input, simplified separation devices, and high efficiency. , To date, researchers have developed single-layer wettability-switchable emulsion separation membranes that are thermosensitive, , pH-responsive, − and photoresponsive. , Zhang et al prepared thermoresponsive poly­( N -isopropylacrylamide)-modified nylon membranes by the hydrothermal method, which could separate at least 16 types of emulsions. Using one-step in situ polymerization of polyaniline monomers in aqueous media, Li et al developed a smart coating with pH-switchable wettability on a variety of general substrates such as polyester mesh, cotton, and sponge, enabling adjustable oil/water separation.…”

A Facile Fabrication of ZnFe2O4/Sepiolite Composite with Excellent Photocatalytic Performance on the Removal of Tetracycline Hydrochloride

“…Hence, large quantities of antibiotics have been found in the soil, surface waters and even drinking water and will eventually threaten the health of humans and livestock through the food chain (Agerstrand et al, 2015;Isari et al, 2020a;Dong et al, 2020). Therefore, the removal of antibiotics from wastewater has been adopted, such as advanced oxidation processes (AOPs), membrane separation, microbial degradation, adsorption and photocatalysis (Debnath et al, 2020;Hayati et al, 2020;Khan et al, 2020;Zhao R. et al, 2020;Zong et al, 2021). Among above techniques, photocatalytic degradation of antibiotics on the surface of photocatalytic has been received a lot of attention because of their simple operation, high efficiency, energy saving, environmental protection and mild reaction conditions (Isari et al, 2020b).…”
