This study focused on generating biodiesel from waste cooking oil (WCO) employing an αFe₂O₃/CuO nanocatalyst synthesized via a co-precipitation method. Several characterization techniques, including FTIR, XRD, SEM-EDX, BET, and TEM analyses, were applied to scrutinize the features of fabricated nanocatalyst. The results confirmed successful incorporation CuO into αFe₂O₃ structure. BET analysis further revealed that addition nanoparticles significantly enhanced catalyst's surface properties, increasing number active sites available for transesterification reactions. Besides, exhibited specific area 334 m²/g, highlighting its high availability catalytic activity. process was statistically optimized using response methodology (RSM) with Box-Behnken design (BBD) assess influence critical reaction parameters. Vital parameters evaluated included temperature (50–70 °C), methanol/WCO molar ratio (8–14 mol/mol), catalyst loading (1–3 wt%). Moreover, ANOVA indicated proportion had most remarkable effect production efficiency, F-value 337.11. Under optimal conditions time 3 h, 11, dosage 2 wt%, 60 °C highest yield 94.27% achieved. Additionally, reusability assessment demonstrated notable stability, only 12% reduction in efficiency observed over seven cycles. research demonstrates nanocatalysts, owing their unique have potential serve as highly effective heterogeneous catalysts transesterification.
