Abstract This study investigates the synthesis and photocatalytic performance of CeO2/porphyrin nanocomposites, created by self-assembling porphyrin monomers onto CeO2 nanoparticles, which were green-synthesized using Cleistocalyx operculatus leaf extract. The resulting composite showed enhanced efficiency for degrading organic pollutants, such as methylene blue rhodamine B, compared to individual nanoparticles free aggregates. characterized SEM, XRD, FTIR, EDX, UV-Vis, confirming successful their crystalline integrity. TCPP (Tetrakis(4-carboxyphenyl)porphyrin) was integrated via a reprecipitation method, SEM XRD analysis verified uniform incorporation preserving nanofiber morphology structure with an average size 9 nm. CeO2/TCPP exhibited extended visible light absorption, shown in UV-Vis diffuse reflectance spectra, indicating its potential applications under light. Photocatalytic tests simulated sunlight demonstrated significant improvement performance, 95.9% degradation Rhodamine B after 120 minutes, particularly at CeO2:TCPP ratio 10:1. research highlights effective synergy between materials, providing novel approach developing efficient, nanocomposites environmental remediation light, marking contribution technology.
