In this paper, a nano-structured Fe3O4@ZIF-8@TiO2 catalyst was prepared via a versatile recipe and then characterized by the Fourier transform infrared spectroscopy (FT-IR) and x-ray diffraction (XRD) analyses. Afterward, the as-synthesized Fe3O4@ZIF-8@TiO2 catalyst utilized for the esterification reaction of oleic acid to produce biodiesel in a batch reactor system. The obtained results revealed that the process efficiency can be achieved to a good conversion of 78% after only 1 h under mild condition of 50 °C temperature along with only 0.125 g Fe3O4@ZIF-8@TiO2 catalyst. Furthermore, effect of various operational parameters on the process efficiency including ethanol/oil molar ratio (10:1, 20:1, and 30:1) and time (5 to 120 min) was investigated to achieve the highest biodiesel production efficiency.
