“…In contrast, heterogeneous catalysts (e.g., zeolites, heteropolyacids, metal oxides, etc.) have attracted growing interest owing to their low pollution and easy recovery ( Woo et al, 2021 ; Zhang et al, 2022b ; Paiva et al, 2022 ; Ul Islam et al, 2022 ). However, high-efficiency separation of the catalyst from the liquid phase and reduction of catalyst loss remain challenges.…”

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.

“…Although the usage of homogeneous catalysts can achieve a high percentage of conversion rates, it also causes some salient problems such as expensive separation stages and large amounts of chemical wastewater [6]. Therefore, heterogeneous catalysts have just been developed for various applications due to their less hazardous, ease of separation, and recyclability [7][8][9].…”

In this work, the novel TPA@C-NiZr-MOF catalyst is synthesized by the impregnation of tungstophosphoric acid (TPA) on the NiZr-based metal-organic framework (NiZr-MOF) followed by calcination up to 300 °C. The as-prepared catalyst materials were structurally, morphologically, and texturally characterized by XRD, FTIR, temperature programmed desorption of NH3 ( TPD-NH3 ), N2 physisorption, SEM, TEM, and XPS. The prepared catalyst can be used as an efficient heterogeneous catalyst for biodiesel production from oleic acid (OA) with methanol. The results indicated that, in comparison to TPA@NiZr-MOF, the TPA@C-NiZr-MOF catalyst calcined at 300 °C exhibits excellent catalytic performance probably owing to the synergistic effect between TPA and metal oxide skeletons, high acidity, as well as larger surface area and pore size. Additionally, the TPA@C-NiZr-MOF catalyst can be reused in up to six cycles with an acceptable conversion. This study showed that the bimetallic MOF-derived composite materials can be used as an alternative potential heterogeneous catalyst toward biorefinery applications.

“…Heterogeneous catalytic approaches have distinct advantages over homogeneous catalytic approaches because the heterogeneous catalysts with excellent reusability can be easily separated from the reaction mixture [13]. Currently, various types of heterogeneous catalysts have been reported for biodiesel production, such as zeolite [14], Amberlyst [15], acidic ionic liquids [16], and heteropoly acid [17,18]. However, in some heterogeneous catalysts, the leaching of active components is found in the reaction process, leading to a decrease in stability [19].…”

In this study, the bimetallic Ni-Zr MOF-derived nickel-zirconium oxide (Ni-Zr-O)-impregnated silicotungstic acid (HSiW) nanocomposite catalyst (HSiW@Ni-Zr-O) was prepared via a hydrothermal procedure followed by a pyrolysis treatment, and its structural, morphological, and surface components and oxidation states were characterized by using XRD, FTIR, TPD-NH3, SEM, TEM, N2 physisorption, and XPS analyses. Then, the nanocomposite catalysts were successfully applied to the esterification of oleic acid (OA) with methanol. According to its characteristics, the obtained HSiW@Ni-Zr-O-1 catalyst would generate larger pores, a higher acidity, and active interfaces at the calcining temperature of 300 °C. Therefore, HSiW@Ni-Zr-O-1 exhibits an excellent catalytic activity of 95.2% under optimal reaction conditions. Additionally, the catalyst can be reused with a good catalytic activity after nine cycles. This study highlights the opportunity of using bimetallic MOFs as precursors to the synthesis of highly nanoporous metal oxide, which supports the larger-industrial scale production of biofuels.
