Abstract

In this report, we demonstrate the advantage of Jatropha curcas plant extract as particle reducing agent in stabilizing cerium oxide (CeO₂) nanoparticles. The toxic-free, green Jatropha curcas extract mediated CeO₂ nanoparticles has tested in photocatalytic degradation of indoor gaseous pollutant acetaldehyde and compared with conventional chemically synthesized CeO₂ nanoparticles (NH₃ and NaOH). The results showed green synthesized CeO₂ nanoparticles are effectively reducing the particle size 3–5 nm and homogenous particle distribution compared to chemically synthesized CeO₂ (18–25 nm). As a result, it exhibits effective photocatalysis performance in acetaldehyde degradation.
