ClearPhotocatalytic strategy to mitigate microplastic pollution in aquatic environments: Promising catalysts, efficiencies, mechanisms, and ecological risks
This review summarizes recent advances in photocatalytic degradation of microplastics, covering catalysts, mechanisms, and reactive oxygen species generation pathways. The authors call for more realistic photocatalytic materials, better mechanistic understanding of degradation intermediates, and quantitative ecological risk assessment of photocatalysis byproducts.
Electrochemical Detection of Microplastics in Aqueous Media

A Review on the Use of Metal Oxide-Based Nanocomposites for the Remediation of Organics-Contaminated Water via Photocatalysis: Fundamentals, Bibliometric Study and Recent Advances
This review examines how metal oxide nanocomposite materials can be used as photocatalysts to break down toxic organic pollutants in contaminated water using light energy. While focused on cleaning up dyes, drugs, and pesticides, the technology is relevant to microplastics because similar photocatalytic approaches are being explored to degrade plastic particles in water. Improving water treatment technologies like these could help reduce human exposure to the cocktail of pollutants, including microplastics, found in water supplies.
Evaluating Microplastic Effects on Performance and Electrochemistry of Microbial Fuel Cells for Wastewater Treatment
Researchers evaluated how microplastics affect the performance of microbial fuel cells used for wastewater treatment.
