Active chloride-mediated PET microplastic depolymerization via ferroelectric electrocatalysis: Unveiling the dark reaction boosting mechanism

Electrochemical degradation of micro/nanoplastics in water: recent results

AI summary · Read the abstract

Researchers reviewed electrochemical oxidation—particularly using boron-doped diamond anodes—as an advanced process capable of degrading micro- and nanoplastics in water with over 90% efficiency under optimized conditions. This technology is important because conventional wastewater treatment plants not only fail to fully remove microplastics but can fragment them into smaller, more bioavailable nanoplastics.

Interfacial capture and electro-Fenton degradation of polyethylene microplastics using a dual-function ferrocene-MOF electrode

Electrochemical removal of PET and PE microplastics for wastewater treatment

AI summary · Read the abstract

Researchers proposed an electrochemical method for degrading polyethylene and PET microplastics in wastewater using electrogenerated active chlorine species. The study developed a shrinking core-based kinetic model to assess the degradation process, offering a potential new approach for removing microplastics during wastewater treatment.

Photocatalytic-Driven Self-Degradation of Polyester Microplastics Under Solar Light

AI summary · Read the abstract

"Researchers synthesized a polyester fiber modified with a g-C3N4/TiO2 photocatalyst that can self-degrade under solar illumination, achieving near-complete breakdown into CO2 and water after 400 hours of light exposure. Designing plastics that decompose under sunlight rather than fragmenting into persistent microplastics offers a proactive materials-level strategy to reduce the volume of synthetic polymer pollution entering ecosystems."
