ClearComparison of Cytotoxicity and Photocatalytic Properties of Iron Vanadate Nanoparticles with Commercial Catalysts: For the Degradation of Microplastics and Bacterial Inactivation Application
Researchers compared iron vanadate nanoparticles with commercial photocatalysts for degrading microplastics and inactivating bacteria using solar light. The iron vanadate catalyst showed moderate cytotoxicity at low concentrations and demonstrated effective photocatalytic activity against both microplastics and bacterial contamination. The study suggests that iron vanadate nanoparticles could serve as a dual-purpose water treatment material for addressing microplastic pollution and microbial contamination simultaneously.
Decomposition of microplastics using copper oxide/bismuth vanadate-based photocatalysts: Insight mechanisms and environmental impacts
Researchers developed a light-activated catalyst using copper oxide and bismuth vanadate that can break down microplastics in wastewater. The treatment effectively degraded the plastic surfaces, though the treated water still needed dilution before being safely discharged due to residual chemicals that were harmful to test organisms. This technology could help reduce microplastic levels in wastewater before it reaches rivers and oceans where it enters the food chain.
The Photocatalytic Degradation of Enrofloxacin Using an Ecofriendly Natural Iron Mineral: The Relationship Between the Degradation Routes, Generated Byproducts, and Antimicrobial Activity of Treated Solutions
This paper is not relevant to microplastics research; it investigates the photocatalytic degradation of the antibiotic enrofloxacin in water using a natural iron mineral, focusing on pharmaceutical contamination rather than plastic particles.
Nanophotocatalytic synergistic degradation of antibiotics and microplastics: Mechanisms, material design, and environmental applications
This review examines how microplastics and antibiotics interact in water during photocatalytic treatment, finding that microplastics can both help (by shuttling electrons) and hinder (by shielding light or hosting biofilms) the degradation process, depending on conditions. Aged microplastics — which have more surface oxygen groups — adsorb more antibiotics, making them tougher composite targets for treatment systems. Understanding these interactions is essential for designing water purification systems that can handle the combined pollution reality of modern waterways.
Humic substance/metal-oxide multifunctional nanoparticles as advanced antibacterial-antimycotic agents and photocatalysts for the degradation of PLA microplastics under UVA/solar radiation
Researchers developed hybrid nanoparticles made from humic substances and metal oxides that can both break down PLA microplastics under UV or sunlight and kill harmful bacteria and fungi. The nanoparticles showed strong photocatalytic activity, degrading microplastics while simultaneously acting as antimicrobial agents. The study suggests these biowaste-derived materials could offer a dual-purpose solution for tackling both plastic pollution and microbial contamination.
Effect of microplastics on tertiary/quaternary treatment of urban wastewater: Fe-biochar/peroxymonosulfate/sunlight vs solar photo-Fenton
Researchers evaluated how microplastics present in secondary-treated urban wastewater affect the degradation of four pharmaceutical micropollutants and the inactivation of antibiotic-resistant E. coli using two advanced oxidation processes. Microplastics were found to influence the performance of both iron-modified biochar/peroxymonosulfate and solar photo-Fenton treatments.
Iron‐Based Catalysts for the Removal of Microplastics
This review evaluates the potential of iron-based catalysts for degrading microplastics in water through photocatalytic, Fenton, and electrocatalytic approaches. Researchers highlight the advantages of iron's abundance, low toxicity, and catalytic versatility for generating reactive oxygen species that can break down plastics. The study identifies challenges including scalability and catalyst recovery while recommending interdisciplinary collaboration to advance iron-based remediation solutions.

Degradation of Micro- and Nano-Plastics by Photocatalytic Methods
This paper reviews photocatalytic methods — using light-activated catalysts — as a way to break down micro- and nano-plastics in the environment. These approaches offer a promising path toward degrading persistent plastic particles that accumulate in marine and drinking water systems.
Functionalized magnetic nanoparticles: Synthesis, characterization, catalytic application and assessment of toxicity
Researchers developed iron-based magnetic nanoparticles as catalysts that can rapidly break down bisphenol A (BPA) — a common plastic additive and endocrine disruptor — in water using a combination of low-dose hydrogen peroxide and UV light, achieving complete degradation in under 15 minutes. The treated water also showed reduced toxicity to human cancer cells, suggesting this approach could help remove persistent chemical pollutants from water supplies.

Photocatalytic and biological technologies for elimination of microplastics in water: Current status
This review examines emerging photocatalytic and biological technologies for breaking down microplastics in water, since conventional treatment facilities can capture but not fully destroy these particles.
