Enhanced sunlight photocatalytic activity and biosafety of marine-driven synthesized cerium oxide nanoparticles.

ABSTRACT: This contribution presents the biosynthesis, physiochemical properties, toxicity and photocatalytic activity of biogenic CeO₂ NPs using, for the first time, marine oyster extract as an effective and rich source of bioreducing and capping/stabilizing agents in a one-pot recipe. CeO₂ NPs formation was initially confirmed through the color change from light green to pale yellow and subsequently, their corresponding absorption peak was spectroscopically determined at 310 nm with an optical band-gap of 4.67 eV using the DR-UV technique. Further, XRD and Raman analyses indicated that nanoceria possessed face-centered cubic arrangements without any impurities, having an average crystallite size of 10 nm. TEM and SEM results revealed that biogenic CeO₂ NPs was appr
