我们报道了钌-钼（MoRu）固溶体合金纳米粒子（NPs）作为1-辛烯和1-辛炔加氢催化活性的应用。通过扫描透射电子显微镜（STEM）结合能量色散X射线光谱（EDX）和粉末X射线衍射（PXRD）测量证实了MoRu NPs的固溶体结构。测试了这些NP在四氢呋喃（THF）中对1-辛炔和1-辛烯的氢化催化活性。Ru与Mo在原子水平上合金化，提高了Ru的加氢催化活性。通过X射线光电子能谱（XPS）研究发现，Ru的电子修饰是通过Mo与Ru之间的电荷转移，引起反应物吸附能的变化，从而提高了催化活性。不饱和碳氢化反应是一个重要的反应，在化学工业中有着广泛的应用。从能量消耗的观点来看，需要能够在温和条件下有效促进反应的催化剂。
We report the hydrogenation catalytic activity application of molybdenum–ruthenium (MoRu) solid-solution alloy nanoparticles (NPs) as catalysts for the hydrogenation of 1-octene and 1-octyne. The solid-solution structure of MoRu NPs was confirmed through scanning transmission electron microscopy (STEM) coupled with energy-dispersive X-ray spectroscopy (EDX), and powder X-ray diffraction (PXRD) measurement. The hydrogenation catalytic activity of these NPs toward 1-octyne and 1-octene in tetrahydrofuran (THF) was tested. The hydrogenation catalytic activity of Ru was enhanced by alloying with Mo at the atomic level. An electronic modification of Ru by a charge transfer from Mo to Ru, which could induce the change in the adsorption energy of reactants resulting in enhanced catalytic activity, was observed by X-ray photoelectron spectroscopy. The hydrogenation of unsaturated carbons is an important reaction that is widely used in the chemical industry. From an energy consumption viewpoint, catalysts that can effectively promote the reaction under mild conditions are required.
