“…The optimum conditions for transesterification were an oil/methanol molar ratio of 1:8, catalyst loading of 11% (w/w), and reaction temperature of 328.15 K for 60 min of reaction time using the response surface method. The study also confirmed that the Ni-doped ZnO nanocatalyst can be reused efficiently for three cycles [79].…”

The development of solid acid catalysts, especially based on metal oxides and different magnetic nanoparticles, gained much awareness recently as a result of the development of different nano-based materials. Solid acid catalysts based on metal oxides are promising for the (trans)esterification reactions of different oils and waste materials for biodiesel production. This review gives a brief overview of recent developments in various solid acid catalysts based on different metal oxides, such as zirconia, zinc, titanium, iron, tungsten, and magnetic materials, where the catalysts are optimized for various reaction parameters, such as the amount of catalyst, molar ratio of oil to alcohol, reaction time, and temperature. Furthermore, yields and conversions for biodiesel production are compared. Such metal-oxide-based solid acid catalysts provide more sustainable, green, and easy-separation synthesis routes with high catalytic activity and reusability than traditionally used catalysts.

Various types of biofuels and feedstocks are considered and discussed in terms of their environmental and economic feasibilities. Biofuel is gaining the centre stage as human activities keep rising and the consequent increase in the discharge of lethal emissions is also a subject of concern. The need to cut down greenhouse gas emissions (i.e. CO 2 ,N 2 O, CO, NO, SO 2) is imperative to preserve our natural biodiversity. Biodiesel and bioethanol are the most common, viable alternatives and infinite green fuels that can be used in internal combustion engine. Biodiesel (commonly from waste cooking oil, nonedible vegetable oil, animal fat and tallow) and bioethanol (usually from forestry waste, Lignocellulosic biomass, starchy and sugary vegetable sources, and agricultural residues) are synthesized from straight vegetable feedstocks to bring their characters close to that of the fossil diesel and gasoline. The candidates as green fuels have the potential to significantly reduce the greenhouse gas emissions by as much as 30% from their combustion in internal combustion engine. The various possible methods used for their productions determine the fuel sensitivity to the environment and the energy balance. In general, the energy balances are positive for both fuel substitutes.

“…In response to this problem, the development of heterogeneous catalysts for biodiesel production is gaining much attention from many researchers due the advantages of heterogeneous catalysts obtained at nanometric scale added to the magnetic property, constitute an appropriate and pertinent contribution to the chemical reactions of transesterification for biodiesel production. Therefore, these heterogeneous catalysts can be easily separated, regenerated, and reused for the further cycle during transesterification process 10,11 . Thus, it reduces the contamination to the environment because lower amount of waste is generated during this process.…”

Summary Biodiesel was successfully produced by transesterification process of soybean oil and methanol using Ni0.5Zn0.5Fe2O4 nanomagnetic catalyst. The Ni0.5Zn0.5Fe2O4 catalyst was synthesized by the combustion method and its properties were investigated using X‐ray diffraction, N2 physisorption at 77 K, Fourier transform infrared analysis, thermogravimetric analysis, scanning electron microscopy, and a transmission electron microscopy. The performance of catalyst was investigated during transesterification reaction for fatty acid methyl esters (FAMEs) production. FAMEs were studied by gas chromatography technique. The effect of reaction conditions such as molar ratio of methanol/soybean oil, catalyst amount, reaction temperature, and reaction time on FAMEs yield was also evaluated. The biodiesel yield of 92.1% was obtained under the following reaction conditions: 9:1 of methanol/soybean oil molar ratio and, 2% of catalyst loading at 180°C in 3 hours. Furthermore, the energy of activation (Ea) was 67.4 kJ.mo1−1 and the pre‐exponential factor (ko) was 8.35 × 104 L mol−1 min−1 determined using Arrhenius equation.
