Visible-Light-Driven Photocatalytic Hydrogen Production from Polystyrene Nanoplastics Using Pd/TiO₂ Nanoparticles.

ABSTRACT: The accumulation of microplastics and nanoplastics in aquatic environments has raised significant concerns in recent years, given the potential health risks to both aquatic ecosystems and humans; due to their nanometer size, they enter the food chain of aquatic species and consequently that of humans too. This study presents an efficient plasmonic photocatalyst for degrading polystyrene nanoplastics (PS NPs), while simultaneously generating green hydrogen in the process. Blank controls show that the presence of PS NPs is necessary for H₂ evolution, since under identical conditions, it does not occur in their absence. A series of visible light-responsive plasmonic photocatalysts consisting of TiO₂ nanoparticles (NPs) supporting Pd, Au, Pt, and Ag NPs were prepared via
