Abstract Recent advancements in membrane-assisted seawater electrolysis powered by renewable energy offer a sustainable path to green hydrogen production. However, its large-scale implementation faces challenges due slow power-to-hydrogen (P2H) conversion rates. Here we report modular forward osmosis-water splitting (FOWS) system that integrates thin-film composite FO membrane for water extraction with alkaline (AWE), denoted as FOWS AWE . This generates high-purity directly from wastewater...
Halides and natural organic matter (NOM) are inevitable in aquatic environment influence the degradation of contaminants sulfate radical (SO4•–)-based advanced oxidation processes. This study investigated formation chlorate coexposure SO4•–, chloride (Cl–), bromide (Br–) and/or NOM UV/persulfate (UV/PDS) cobalt(II)/peroxymonosulfate (Co/PMS) systems. The increased with increasing Cl– concentration UV/PDS system, however, Co/PMS it initially then decreased. involved hypochlorous...
Photolysis of free chlorine (HOCl/ClO–) is an advanced oxidation process (AOP) to produce hydroxyl (HO•) and other radicals for refractory micropollutant degradation. However, HOCl/ClO– only conducive activation production by ultraviolet (UV) light. For the first time, we show use visible light (>400 nm) HO• ClO•, through graphitic carbon nitride (g-C3N4) photogenerated hvb+, ecb–, O2•– in presence HOCl/ClO–, which was termed g-C3N4-enabled AOP (VgC-AOP). The VgC-AOP increased pseudo...
In recent years, there has been growing interest in the varied applications of nanobubble technology. Given their unique physicochemical properties, such as minuscule size (< 1 µm), surface charge, and high internal pressure, nanobubbles (NB) could provide new opportunities fields environmental engineering (including remediation, water treatment, aerobic fermentation, anaerobic digestion, algal biomass production), agriculture agronomy, horticulture, aquaculture, aquaponics, bioponics,...
Permanganate was activated by ultraviolet (UV) photolysis at 254 nm, resulting in the efficient degradation of micropollutants. The four probe molecules (i.e., nitrobenzene, benzoic acid, terephthalic and p-chlorobenzoic acid) two micropollutants gemfibrozil nalidixic resistant to permanganate oxidation enhanced UV/permanganate system, with pseudo-first-order rate constants (k′) 0.065–0.678 min–1 under experimental conditions. Hydroxyl radicals (HO•) Mn(V) peroxide, which were produced...
Abstract Coupling photocatalyst-coated optical fibers (P-OFs) with LEDs shows potential in environmental applications. Here we report a strategy to maximize P-OF light usage and quantify interactions between two forms of energy (refracted evanescent waves) surface-coated photocatalysts. Different TiO 2 -coated quartz (TiO -QOFs) are synthesized characterized. An balance model is then developed by correlating different nano-size coating structures propagation modes -QOFs. By reducing...

The ultraviolet (UV)/chlorine process has attracted increasing attention for micropollutant abatement. However, the limited hydroxyl radical (HO•) generation and formation of undesired disinfection byproducts (DBPs) are two major issues in this process. This study investigated roles activated carbon (AC) UV/chlorine/AC-TiO2 abatement DBP control. degradation rate constant metronidazole by was 3.44, 2.45, 1.58 times higher than those UV/AC-TiO2, UV/chlorine, UV/chlorine/TiO2, respectively. AC...
Mold infestations on surfaces present significant challenges to public health. Germicidal UV-C irradiation effectively inactivates spores suspended in water, yet information surface spore mitigation is surprisingly absent. We show the effectiveness of 265–275 nm light mitigateAspergillus nigeron nutrient-rich surfaces. molds differs from inactivating water due unique characteristics mycelial structures. Complete preinactivation all viable cells during exposure crucial prevent mycelia...
A photocatalyst-coated optical fiber was coupled with a 318 nm ultraviolet-A light emitting diode, which activated the photocatalysts by interfacial photon-electron excitation while minimizing photonic energy losses due to conventional photocatalytic barriers. The delivery mechanism explored via modeling of evanescent wave produced upon total internal reflection and photon refraction into TiO2 surface coating. This work explores aqueous phase LED-irradiated fibers for treating organic...
