“…After oxidation, the specific surface area, cumulative pore volume, and cumulative pore area for OLF are increased, where the specific surface area reaches 73.63 m 2 /g and the cumulative pore area is increased to 137.38 m 2 /g, which represent an increase of 264.50% and 256.83%, respectively. This may be due to the increase in the layer spacing of the OLF multilayer structure during oxidation, resulting in an increase in the surface area (Ding et al, 2019). The higher specific surface area indicates that the carrier of the same mass has a larger surface area and can load more activators.…”

“…Zheng et al prepared a carbon nanotube-based SPE reactor catalyst using the ethylene glycol reduction method, and the results showed that the best catalytic activity was obtained for 40 mg/ml chloroplatinic acid and 300 W ultrasonic power (Zheng et al, 2018). In addition, Ding et al used graphene-loaded Pt as an SPE reactor cathode catalyst for the hydrogenation of soybean oil and obtained a product with TFA contents of 1.53% and 111.3 g I 2 /100 g (Ding 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.

“…Given its high surface area, graphene is also a good substrate for dispersing metal particles and producing metal-carbon hybrids with improved electrocatalytic activity. In this regard, electrochemical studies based on graphene/platinum materials have been widely reported [14][15][16][17][18][19][20]. In the present work, an open-pore graphite foam electrode (GFE) was electrochemically modified with RGO and Pt particles to improve its electrochemical properties while maintaining the 3D structure of the graphite foam.…”

This paper aimed to improve the electrochemical activity of a pitch-derived open-pore graphite foam (GF) by an electrochemical coating of reduced graphene oxide (RGO) and platinum particles without significantly affecting its 3D-structure. RGO was synthesized using cyclic voltammetry (CV) from a 3 g L−1 GO and 0.1 M LiClO4 solution. For the electrodeposition of Pt particles, an alternating current method based on electrochemical impedance spectroscopy (EIS) was used. A sinusoidal voltage from a fixed potential Ei was varied following a selected amplitude (ΔEac = ± 0.35 V) in a frequency range of 8 Hz ≤ fi ≤ 10Hz, where i = 500. This method proved its efficiency when compared to the traditional CV by obtaining more highly electroactive coatings in less synthesis time. For samples’ characterization, physical measures included permeability, pressure drop, and nitrogen adsorption isotherms. The electrochemical characterization was performed by CV. The surface morphology and chemical composition were examined using field emission electron microscopy (FESEM) and energy-dispersive X-ray spectroscopy (EDX), respectively. RGO improved the electron transfer rate constant of GF, and a more homogeneous coating distribution of reduced size Pt particles was obtained.

“…The Pt/CNT catalyst was more durable and stable than the Pt-C catalyst. Similarly Ding et al (2019) synthesized and used Pt/Gr nanocomposite as cathode in a solid polymer electrolyte reactor. The authors observed that soybean oil obtained by electrochemical hydrogenation had 1.53% final TFA content.…”

Trans fats are desired by the edible oil industry as they impart firmness, plasticity, and oxidative stability to oil. However, clinical trials have demonstrated the adverse effects of trans fats in food on human health and nutrition. Regulatory actions have been taken up by government and non‐government bodies worldwide to eliminate the presence of trans fats in the food supply. The World Health Organization (WHO) has launched a “REPLACE” action plan to eliminate trans‐fat from the global food industry by 2023. A few enabling technologies are developed to mitigate trans fats namely, trait‐enhanced oils, modification in the hydrogenation process, interesterification, fractionation, blending, and oleogelation. Some of them have the drawback of replacing trans‐fat with saturated fats. Interesterification and oleogelation are in‐trend techniques with excellent potential in replacing trans fats without compromising the desired functionality and nutritional quality attributes. This review presents an overview of trans fatty acid for example, its dietary intake in food products, possible adverse health impact, regulations, and approaches to reduce the usage of trans fats for food application. Practical Application The requirement for the replacement of trans fatty acids (TFAs) in food supply globally has challenged the food industry to find a novel substitute for trans fats without compromising the desired functionality and nutritional property. This review presents detailed background on trans fats, their health impacts and current trends of reformulation of oils and fats to mitigate their presence in food supply chains. Information compiled in this paper will help food scientists and technologists, chemists, food processors, and retailers as there is an urgent need to find novel technologies and substitutes to replace trans fats in processed foods.
