“…In particular, the Fe 3 O 4 @ SBA-15-NH 2 -HPW exhibited a high biodiesel yield of 91% under optimal reaction conditions, and also exhibited high reusability. Ghasemzadeh et al (2022) adapted a cotton/Fe 3 O 4 @SiO 2 @ H 3 PW 12 O 40 magnetic nanocomposite to catalyze the transesterification of sunflower oil. The catalyst had an excellent magnetism of 45 emu/g and demonstrated a high FAME yield of 95.3% under optimum conditions.…”

In this study, we summarize recent advances in the synthesis of magnetic catalysts utilized for biodiesel production, particularly focusing on the physicochemical properties, activity, and reusability of magnetic mixed metal oxides, supported magnetic catalysts, ionic acid-functionalized magnetic catalysts, heteropolyacid-based magnetic catalysts, and metal–organic framework-based magnetic catalysts. The prevailing reaction conditions in the production of biodiesel are also discussed. Lastly, the current limitations and challenges for future research needs in the magnetic catalyst field are presented.

“…The activity test showed that a biodiesel yield of 95.4% was obtained in 4 h at 164 • C. The MoO 3 /SrFe 2 O 4 catalyst could be easily separated by a permanent magnet and showed high stability with a yield of 84% after five cycles. A magnetic cotton powder with high dispersion, high porosity, and high magnetic properties was prepared using a co-precipitation method and covered with tetraethyl orthosilicate (TEOS) on the surface of silica to form Cotton/Fe 3 O 4 @SiO 2 by Matin et al [146]. Finally, nanocatalyst-structured catalysts were prepared using the phosphotungstic acid (HPW) impregnation method and used for the preparation of biodiesel.…”

With the rapid development of industry and the increasing demand for transportation, traditional sources of energy have been excessively consumed. Biodiesel as an alternative energy source has become a research focus. The most common method for biodiesel production is transesterification, in which lipid and low carbon alcohol are commonly used as raw materials, in the presence of a catalyst. In the process of transesterification, the performance of the catalyst is the key factor of the biodiesel yield. This paper reviews the recent research progress on homogeneous and heterogeneous catalysts in biodiesel production. The advantages and disadvantages of current homogeneous acid catalysts and homogeneous base catalysts are discussed, and heteropolyacid heterogeneous catalysts and biomass-derived base catalysts are described. The applications of the homogeneous and heterogeneous catalyst derivatives ionic liquids/deep eutectic solvents and nanocatalysts/magnetic catalysts in biodiesel production are reviewed. The mechanism and economic cost of current homogeneous acid catalysts and homogeneous base catalysts are also analyzed. The unique advantages of each type of catalyst are compared to better understand the microscopic details behind biodiesel. Finally, some challenges of current biodiesel catalysts are summarized, and future research directions are presented. This review will provide general and in-depth knowledge on the achievements, directions, and research priorities in developing novel homogeneous/heterogeneous catalysts for the green and cost-effective production of biodiesel.
