Abstract
This research discusses the development of magnetic materials as an effort to produce renewable catalysts in overcoming the energy crisis. The purpose of this study was to synthesize and characterize MgO/CoFe2O4 nanoparticles using the coprecipitation method. The synergy between substances that are catalysts, namely MgO and CoFe2O4 to MgO/CoFe2O4 was expected to produce a superior catalyst for biodiesel production. The stages of this research were to synthesize MgO nanoparticles and CoFe2O4 nanoparticles by coprecipitation and continued with MgO impregnation on the CoFe2O4 surface to become MgO/CoFe2O4 with a mole ratio of 5: 1, then characterize them using X-Ray Diffraction and Scanning Electron Microscopy. The results of XRD analysis showed that MgO/CoFe2O4 nanoparticles were successfully synthesized according to the standard curves of MgO and CoFe2O4 (JCPDS Cards No. 89-7746 and 22-1086). SEM analysis results show that impregnated particles have spherical morphology and are larger in size than the two constituent components. The mean particle sizes of MgO, CoFe2O4, and MgO/CoFe2O4 were 29.588 nm, 42.282 nm and 65.953 nm, respectively. EDX analysis shows the appropriate atomic percentage and mass of each of the constituents of MgO/CoFe2O4 namely Magnesium, Iron, Cobalt, Oxygen.
