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.
