Bioinspired hierarchical electrospun TiO2/BiOI nanofibers for multifunctional photocatalytic PMS activation: Antibiotics and microplastics removal

AI summary · Read the abstract

Scientists engineered a special material (tiny fibers made of titanium dioxide and a light-sensitive compound) that, when activated by regular visible light, can break down two nasty water pollutants at once: antibiotic residues and microplastic particles. In lab tests, this material removed nearly all traces of an antibiotic and other contaminants from water, and it also broke down tough plastic particles into smaller fragments—all while staying reusable for at least nine rounds without falling apart or leaching harmful metals. This matters because current water treatment plants struggle to remove both antibiotics (which fuel drug-resistant bacteria

Efficient Photocatalytic Degradation of the Persistent PET Fiber-Based Microplastics over Pt Nanoparticles Decorated N-Doped TiO2 Nanoflowers

AI summary · Read the abstract

A photocatalytic approach using platinum-decorated nitrogen-doped TiO2 nanoflowers achieved roughly 29% weight loss in PET fiber microplastics following hydrothermal pretreatment, outperforming untreated samples by about 8-fold. This chemical degradation strategy provides a promising pathway for breaking down one of the most abundant synthetic microplastic types found in textile wastewater and urban sewage.

Photocatalytic Degradation of Organic Pollutants and Microplastics Using Ag/TiO2: Recent Advances in Mechanism, Synthesis and Properties

AI summary · Read the abstract

This study reviewed how silver-modified TiO2 (Ag/TiO2) photocatalysts enhance the degradation of organic pollutants and microplastics by improving light absorption and charge separation compared to TiO2 alone. Developing efficient photocatalytic systems like Ag/TiO2 is a promising pathway for breaking down persistent microplastic particles in water and soil environments where conventional treatment methods fall short.
