“…After hydrogenation in the SPE reactor, the content of linolenic and linoleic acids decreased and the content of oleic and stearic acids increased in both hydrogenated products, as shown in Table 7. This is similar to the hydrogenated soybean oil obtained by the electrochemical process prepared by Wang et al under a high‐pressure H 2 environment (Wang et al, 2019), indicating that 18‐carbon fatty acids are mainly involved in the reaction during the hydrogenation process, and the changes in fatty acids are consistent with the theoretical model of oil hydrogenation proposed by Albright (1970). In addition, the change in linoleic acid in Pt/OLF‐hydrogenated oil is more significant than that in Pt/C‐hydrogenated oil, which may be related to the higher SLo content of Pt/OLF.…”

“…The composition of fatty acids in the samples was determined by gas chromatography (7890A, Agilent, USA) using 1 ml/min of high purity nitrogen as the carrier gas and a split syringe (1:100). The injection port was set at 240°C, and the column was maintained at 180°C for 90 min and then ramped up to 210°C at 30°C/min and maintained for 3 min (Wang et al, 2019).…”

In this study, Pt/OLF catalysts were synthesized using onion‐like fullerenes (OLF) as carriers and applied as cathode catalysts in solid polymer electrolyte (SPE) electrochemical reactors for the preparation of hydrogenated oils. The results show that OLF is a good carrier, and the specific surface area and accumulated pore area of OLF are increased after oxidation by 264.50% and 256.83%, respectively. The loaded Pt forms uniformly dispersed crystalline particles (14.59 nm) on the OLF, and the crystallization is dominated by 111 crystalline planes. In the hydrogenation process, the Pt/OLF catalyst shows lower trienoate selectivity, lower activation energy (21.36 kJ/mol), and higher catalytic activity than the Pt/C catalyst. In addition, the hydrogenated product prepared with the Pt/OLF catalyst has a lower trans fatty acids (TFA) content than that of Pt/C, and the oil crystallization in the product is more uniform, but no difference in flavor is found for the Pt/C‐hydrogenated oil, which is an excellent quality hydrogenated product. Novelty impact statement Preparation of Pt‐based catalyst with good catalytic activity using onion‐like fullerenes (OLF) as carrier. Application of Pt/OLF catalyst to SPE electrochemical hydrogenation reactor to hydrogenated soybean oil. Prepared a hydrogenated product with low trans fatty acids, uniform crystallinity, and good quality.

Rapid industrialization is consuming too much energy, and non-renewable energy resources are currently supplying the world’s majority of energy requirements. As a result, the global energy mix is being pushed towards renewable and sustainable energy sources by the world’s future energy plan and climate change. Thus, hydrogen has been suggested as a potential energy source for sustainable development. Currently, the production of hydrogen from fossil fuels is dominant in the world and its utilization is increasing daily. As discussed in the paper, a large amount of hydrogen is used in rocket engines, oil refining, ammonia production, and many other processes. This paper also analyzes the environmental impacts of hydrogen utilization in various applications such as iron and steel production, rocket engines, ammonia production, and hydrogenation. It is predicted that all of our fossil fuels will run out soon if we continue to consume them at our current pace of consumption. Hydrogen is only ecologically friendly when it is produced from renewable energy. Therefore, a transition towards hydrogen production from renewable energy resources such as solar, geothermal, and wind is necessary. However, many things need to be achieved before we can transition from a fossil-fuel-driven economy to one based on renewable energy.

“…For example, the electrochemical hydrogenation of soybean oil has been reported, with an iodine value of 101.3 gI 2 /100 g at a current of 125 mA (Yu et al, 2017). More recently, when the electrochemical treatment was performed at 50°C for 7.5 hr with a rotary speed of 300 rpm and a current of 120 mA, the IV of the hydrogenated soybean oil was 99.6 gI 2 /100 g oil, and the TFA content was reduced to 4.3% (Wang et al, 2019).…”

Using cold-pressed walnut cake as a raw material, an oil-containing walnut emulsion is prepared and processed in an electrochemical reaction system. The electrochemical treatment conditions are optimized via the superposition of contour lines on the response surface.Under the optimal conditions of 120 min at a temperature of 60°C and a current density of 10 mA/cm 2 , the iodine value is shown to decrease by 28.12%, the nitrogen solubility index to increase by 9.16%, the content of linoleic acid in unsaturated fatty acids to decrease by 16.71%, and the linolenic acid to decrease by 7.81%. After storage at 25°C for 24 weeks, the peroxide value is only 5.57 meq O 2 /kg oil. This demonstrates that the solubility and oxidation stability of the oil-containing walnut powder have been improved by the electrochemical treatment, thereby prolonging the shelf life of the walnut powder, and providing a theoretical basis for the market application and industrial promotion of walnut cake.
