The samples were calcined at 900 &amp;deg;C to ensure a coherent structure with high catalytic performance. Characterization of the catalysts was verified by Xray diffraction (XRD) and Fouriertransform infrared spectroscopy (FTIR). The effect of catalysts on biodiesel content from jatropha oil was studied under supercritical conditions. The results showed that ZnO&amp;gamma;Al2O3 was the superior catalyst for jatropha oil with 98.05 biodiesel under reaction conditions of 7 min reaction time, 140 oil to methanol molar ratio, 6 wt of catalyst loading, 90 bar of reaction pressure, and 300 &amp;deg;C of reaction temperature, compared to 95.50 with La2O3&amp;gamma;Al2O3 at the same parameters. For this study, ZnO&amp;gamma;Al2O3 was the most suitable catalyst due to performance and cost considerations.</abstract> <index>Open Science Index 204, 2023</index> </article>
