Efficient photocatalytic mineralization of polymethylmethacrylate and polystyrene nanoplastics by TiO2/β-SiC alveolar foams

Ti-Modified LaFeO3/β-SiC Alveolar Foams as Immobilized Dual Catalysts with Combined Photo-Fenton and Photocatalytic Activity

“…While β-SiC foams have received strong interest for immobilizing titania photocatalysts [17][18][19][20][21][22][23] , to date only scarce works have reported on their use -and more globally on the use of alveolar foams -as support for Fenton-like catalysts. For example, magnetite powder onto Ni and FeCrAl 24 , BiFeO3/Ni 25 , sludge carbon/SiC 26 , ferrisilicate/SiC 27 or Fe-ZSM-5/SiC 28 have been reported as dark-Fenton foam catalysts for CWPO.…”

Challenges and opportunities for microplastic and nanoplastic removal from industrial wastewater

“…While efficient NPs removal technologies remain underdeveloped, advanced oxidation processes (AOPs) represent attractive technologies for NPs degradation (Zhao et al, 2007, Talvitie et al, 2017, Allé et al, 2021. Use of AOPs for environmental applications, have been precisely defined by Glaze et al (1987) as water treatment processes performed at room temperature and atmospheric pressure, based on the in-situ generation of a powerful oxidizing agent, such as hydroxyl radicals (OH°), at a sufficient concentration to effectively decontaminate waters.…”

Microplastics in aquatic systems, a comprehensive review: origination, accumulation, impact, and removal technologies

“…226 Less common materials have also been investigated such as a PMS carbon nanospring based catalyst and hydroxy-rich ultrathin sheets 227,228 and TiO 2 supported on b-SiC alveolar foams. 229 Fenton and Fenton-like treatment. Fenton based AOPs combine hydrogen peroxide and Fe(II) ions to produce oxidizing hydroxyl radicals, activated by light or heat.…”
