FeCl3-activated biochar catalyst for heterogeneous Fenton oxidation of antibiotic sulfamethoxazole in water

A More Efficient Method for Preparing a MIP-CQDs/ZnO1–x Photodegradant with Highly Selective Adsorption and Photocatalytic Properties

“…At present, antibiotics have been widely used in human and veterinary medicine, and a large amount of untreated residual antibiotics flow into surface water and groundwater, ultimately returning to human drinking water sources and causing serious harm to humans and the ecological environment. , Therefore, it is urgent to develop effective and advanced technologies to treat antibiotics in water bodies. The traditional techniques for treating antibiotics mainly include biodegradation, physical adsorption, membrane separation, chemical oxidation, , etc. However, due to the antibacterial properties and stable chemical structure of antibiotics, commonly used traditional methods are difficult to completely decompose antibiotics and may also produce superbacteria and secondary pollution. , As a rising cure treatment technology, semiconductor photocatalytic technology is considered a promising antibiotic treatment technology due to its easy to obtain reaction conditions (light and room temperature), strong redox ability, and environmental safety. , In addition, it is additionally extensively identified for its low cost, high efficiency, and environmental friendliness. , The photocatalytic activity of semiconductor photocatalyst technology mainly depends on the choice of semiconductor photocatalyst.…”

Simple One-Step Synthesis of Nipa Frond-Derived Magnetic Porous Carbon for Decolorization of Acid Yellow 23

“…Among AOPs, the low-cost Fenton process, which uses Fe 2+ ions as a catalyst and H 2 O 2 as an oxidation agent, has been widely utilized [14]. In this catalysis, Fe 2+ ions can accelerate the breakdown of H 2 O 2 into powerful hydroxyl radicals (•OH) for nonselective oxidation of organic species [15]. However, Fe 2+ ions can generate waste sludge that is difcult to reuse [16].…”

“…Due to their favorable interaction with organic molecules in wastewater, carbonbased materials have been extensively explored as efective supports for Fe-based particles [22]. Compared with synthetic carbon materials like graphene, carbon nanotubes, and nanoporous carbon, biomass-derived porous carbon (PC) is recognized as an inexpensive, sustainable, and ecofriendly support for heterogeneous Fenton catalysts [15,23,24].…”

“…MPC is traditionally prepared in two steps: pyrolysis of biomass into pristine PC and chemical dispersion of magnetic particles over pristine PC [31]. In general, these procedures are time-and energy-consuming [15]. Additionally, magnetic particles could obstruct existing pores in carbon supports, thereby reducing their surface area and pore volume.…”

Removal of typical pollutant ciprofloxacin using iron–nitrogen co-doped modified corncob in the presence of hydrogen peroxide

“…(1) With electron-rich oxygen-containing functional groups and abundant persistent free radicals (PFRs), BCs can act as electron donors to directly provide electrons to facilitate Fe( iii ) reduction. 25 (2) The chemical bond formed between the BCs and the iron-containing material can lower the redox potential of Fe( iii ), which is favorable for the reduction of Fe( iii ). 26 In addition, the application of pristine biochar in advanced oxidation systems is limited because of poor types of functional groups.…”
