Partial hydrogenation of carbon–carbon double bonds is among one of the approaches to improve the low oxidative stability of vegetable biodiesel, which is an important drawback in biodiesel technology. In the current work, we developed an efficient two-phase catalytic system utilizing Pd(OAc)2 dissolved in polyethylene glycol (PEG) that in situ generates palladium nanoparticles in order to promote a selective partial hydrogenation reaction of methyl linoleate into mono-hydrogenated compounds while avoiding the generation of saturated compounds. High yield of methyl oleate was also obtained by hydrogenation of sunflower oil biodiesel using the same catalytic system. Through evaluating the palladium nanoparticles by TEM analysis, it is observed that 4 nm palladium nanoparticles generated in situ in PEG4000 showed high selectivity both for the partial hydrogenation of methyl linoleate and sunflower oil biodiesel.

“…Various materials such as carbon, alumina, silica, titania, iron oxides, etc., have been used as catalyst supports 11 . Among them, iron oxide nanoparticles (Fe 3 O 4 , γ‐Fe 2 O 3 ) have received considerable attention in the last decade because of their ability to combine the mesoporous and magnetic properties 12 . Therefore, the catalysts based on such magnetic nanoparticles pose a good dispersibility in solutions and can be rapidly separated from liquid phase with an external magnet 13 .…”

Recently, magnetic nanoparticles have attracted the attention as catalyst supports due to the possibility of magnetic separation, allowing for easy, fast, and clean recovery of the catalysts. A synthesis strategy of such supports plays an important role in improving the properties of the magnetic catalysts. Here, we proposed a simple and effective method to increase the activity and lifetime of the Pd magnetic catalyst. Polyvinylpyrrolidone‐maghemite nanoparticles were synthesized via one‐pot coprecipitation method using an excess of the NaOH. This was followed by adsorption of Pd2+ on the magnetic nanoparticles. The resulting catalyst showed activity (WCC = 4.0 × 10−6 mol s−1, WCC = 12.7 × 10−6 mol s−1) and selectivity (94%) in phenylacetylene hydrogenation. The catalyst was then magnetically recovered and reused 58 times. The activity of the catalyst increased significantly during the first three runs, changing the rate ratio of WCC to WCC from 1:3.2 to 1:1.6, and then decreased in the following runs. To understand the reason for this behavior, the catalyst was characterized, as well as catalytic studies were performed using similar catalysts for comparison. The results show that the NaOH adsorbed on magnetic support affects the size, stability, and catalytic properties of the Pd particles, and the effect of alkali is enhanced in the presence of the polymer.

“…One of the promising areas of application of magnetic nanoparticles is design of catalysts. The uses of such nanoparticles as a support provides high effectiveness of disperse catalytic systems and the easiness of their separation from the reaction medium by magnetic field [4][5]. Platinum [6][7][8], palladium [9][10][11] and ruthenium [12,13] are the most often used active phase of such type of catalysts.…”
