Bimetallic iron-ruthenium nanoparticles embedded in an acidic supported ionic liquid phase (FeRu@SILP+IL-SO H) act as multifunctional catalysts for the selective hydrodeoxygenation of carbonyl groups in aromatic substrates. The catalyst material is assembled systematically from molecular components to combine the acid and metal sites that allow hydrogenolysis of the C=O bonds without hydrogenation of the aromatic ring. The resulting materials possess high activity and stability for the catalytic hydrodeoxygenation of C=O groups to CH units in a variety of substituted aromatic ketones and, hence, provide an effective and benign alternative to traditional Clemmensen and Wolff-Kishner reductions, which require stoichiometric reagents. The molecular design of the FeRu@SILP+IL-SO H materials opens a general approach to multifunctional catalytic systems (MM'@SILP+IL-func).
嵌入酸性负载离子液体相（FeRu@SILP+IL-SO₃H）的双金属铁-钌纳米颗粒可作为多功能催化剂，用于芳香族底物中羰基的选择性加氢脱氧反应。该催化剂材料由分子组分系统组装而成，结合了酸位点和金属位点，能够在不氢化芳香环的情况下实现C=O键的氢解。所得材料对于多种取代芳香酮中C=O基团催化加氢脱氧生成CH单元具有高活性和稳定性，因此，为需要化学计量试剂的传统克莱门森还原反应和沃尔夫-基什纳还原反应提供了一种有效且温和的替代方法。FeRu@SILP+IL-SO₃H材料的分子设计为多功能催化体系（MM'@SILP+IL-func）开辟了一条通用途径。
