The phyto-Fenton process, which generates hydroxyl radicals through Fenton and Fenton-like reactions using plant-derived hydrogen peroxide (H2O2) ferrous iron (Fe (II)) can degrade organic pollutants. Duckweed, an aquatic plant, is promising for a co-beneficial phytoremediation process that combines wastewater treatment biomass production biofuel feedstock. However, the duckweed has not been extensively studied. Because sulfamethoxazole (SMX), major antibiotic, distributed widely emerging contaminant, its effective removal from contaminated water necessary. present study investigated possibility of simultaneous efficient SMX polluted fuel feedstock by duckweed. This first attempt to demonstrate co-benefits Intracellular H2O2 was produced four duckweeds, Lemna aequinoctialis, L. minor, Landolina punctata, Spirodela polyrhiza, in range 16.7–24.6 μ mol g−1 fresh weight, extracellular released into phase. Consequently, could be used as supply source process. Specifically, 0.5 g almost completely eliminated 1 mg L−1 after 5 d 50 mL sterile modified Hoagland solution containing 10 mM Fe (II). (II)-dependent elimination indicated occurrence reaction. effectively removed SMX. S. polyrhiza similarly even sewage effluent other contaminants. During this treatment, generated at 7.95 dry weight m−2 d−1, converted methane 353 normal liters CH4 kg−1 volatile solids anaerobic digestion. For time, clearly demonstrates potential SMX-contaminated

Mechanistic Insights into Simultaneous Oxygen-Doped and Defect-Engineered Carbon Nitride as a Multifunctional Photocatalyst for Tetracycline Degradation, N₂ Fixation, and H₂O₂ Production

Industrial & Engineering Chemistry Research, Год журнала: 2024, Номер 63(44), С. 18975 - 18988

The ease of synthesis affordable photocatalysts activated by visible light and exhibiting exceptional photocatalytic performance is highly advantageous for addressing energy environmental problems. Herein, simultaneous oxygen-doped defect-engineered carbon nitride (ACN) was easily prepared via thermal calcination using ammonium oxalate as the chemical functionalization agent. experimental studies claimed a maximum tetracycline degradation 88% in 60 min irradiation. ACN displayed 721 μM H2O2 316 ammonia generation illumination. remarkable efficiency photocatalyst linked to its enhanced utilization, achieved modifying bandgap. Also, increased surface area facilitates better charge carrier separation, while defect formation concurrent oxygen doping work suppress recombination. Scavenger highlighted critical role superoxide radicals electrons photocatalysis process. Nitrogen defects heteroatoms facilitate effective separation forming electron–hole pairs within delocalized system under light, which promotes interfacial contact decomposition tetracycline. A metal-free, chemically functionalized photocatalyst, enriched with doped oxygen, employed an affordable, efficient, environmentally friendly material remediation.
