The hydrogenation of vegetable oil-derived compounds using ion-exchange resin-supported ruthenium nanoparticles is reported for the first time. These supported metal catalysts (Ru_DOWEX2-X) were prepared by a simple two-step procedure using commercial and cheap materials, affording high efficiency with a low metal loading. They were characterized by several physicochemical techniques and showed well-dispersed ruthenium nanoparticles into robust beads of the strong cation-exchange resin DOWEX2-X. Their catalytic activity was evaluated for the hydrogenation of methyl undecenoate in heptane under mild experimental conditions (30 °C, 10 bar of H2), and the high activities of the metal solid catalysts deeply depended on the amount of water inside the pores. In terms of recyclability, several physicochemical analyses after successive catalytic runs showed the robustness of the immobilized ruthenium nanoparticles, for which very low metal leaching and no particle aggregation were observed. The decrease in the catalytic activity could be explained by progressive water loss contained in the resin pores, which was illustrated by a decrease in the bead diameter. The immobilized ruthenium nanoparticles were also evaluated in the catalytic hydrogenation of vegetable oils and their corresponding methyl esters and showed a remarkably high activity compared to other catalytic systems tested under similar mild reaction conditions.

使用离子交换树脂负载的钌纳米颗粒催化加氢衍生植物油：范围和局限性
首次报道了使用离子交换树脂负载的钌纳米颗粒对植物油衍生化合物进行氢化。这些负载型金属催化剂 (Ru_DOWEX 2 - X ) 通过简单的两步程序使用商业和廉价材料制备，提供高效率和低金属负载。它们通过多种物理化学技术进行了表征，并显示出分散良好的钌纳米粒子进入强阳离子交换树脂 DOWEX 2 - X的坚固珠粒中。在温和的实验条件下（30 °C，10 bar H 2)，而金属固体催化剂的高活性很大程度上取决于孔内的水量。在可回收性方面，连续催化运行后的几项物理化学分析表明固定化钌纳米粒子的稳健性，观察到非常低的金属浸出且没有粒子聚集。催化活性的降低可以通过树脂孔中所含的逐渐失水来解释，这通过珠粒直径的减小来说明。固定化的钌纳米粒子还在植物油及其相应甲酯的催化氢化中进行了评估，与在类似温和反应条件下测试的其他催化系统相比，显示出非常高的活性。
