In the current research, MgO/MFS nanocatalyst was used in the transesterification process to produce green fuel from vegetable oil. The effect of various synthesis methods such as precipitation, hydrothermal, conventional combustion, and microwave combustion on the magnesium ferrite nanostructure support was investigated. MgO active phase was then impregnated on the support. Synthesized nanocatalysts were characterized by BET-BJH, FTIR, XRD FESEM, and EDX-Dot mapping techniques, and the best performance was staged by the combustion method while the microwave synthesized sample is slightly more active. This catalyst had fine pore size distribution, sheet-like morphology, appropriate roughness (4.6 nm) in the range of 500 nm, and the highest specific surface area (140 m²/g), which 95.4 % of sunflower seed oil was converted to FAMEs. This nanocatalyst was also more stable in the successive reaction conditions than the conventionally combustion synthesized sample which shows the superiority of this heating method in combustion synthesis.

在当前的研究中，MgO / MFS纳米催化剂用于酯交换反应过程中，以植物油为原料生产绿色燃料。研究了沉淀，水热，常规燃烧和微波燃烧等各种合成方法对镁铁氧体纳米结构载体的影响。然后将MgO活性相浸渍在载体上。通过BET-BJH，FTIR，XRD FESEM和EDX-Dot映射技术对合成的纳米催化剂进行了表征，并通过燃烧方法获得了最佳性能，而微波合成样品的活性稍高。该催化剂具有良好的孔径分布，片状形态，在500 nm范围内合适的粗糙度（4.6 nm）和最高比表面积（140 m ^2）/ g），其中95.4％的葵花籽油已转化为FAME。该纳米催化剂在相继反应条件下也比常规燃烧合成样品更稳定，这显示了该加热方法在燃烧合成中的优越性。
