首次通过一锅法合成了高度有序的含Ru介孔碳（Ru-OMC）。与我们之前报道的Ir-OMC相比，Ru前体必须在甲醛与间苯二酚缩聚消耗后添加，以获得小粒径。采用 X 射线衍射 (XRD)、N2 吸附-脱附和透射电子显微镜 (TEM) 对所得不同 Ru 含量的 Ru-OMC 样品进行了表征。结果证明了高度有序的介观结构的形成，其中嵌入了钌颗粒。新型碳材料在肉桂醛选择性加氢（CMA）中进行了进一步评估。与传统的 Ru/AC 催化剂相比，我们的 Ru-OMC 样品表现出更高的活性（2-14 倍），对肉桂醇 (CMO) 的选择性高达 60%。
Highly ordered Ru-containing mesoporous carbons (Ru-OMC) were for the first time synthesized by a one-pot method. Comparing with our previously reported Ir-OMC, the Ru precursor must be added after the formaldehyde was consumed by polycondensation with resorcinol to obtain a small particle size. The resultant Ru-OMC samples with different Ru contents were characterized with X-ray diffraction (XRD), N2adsorption-desorption, and Transmission electron microscopy (TEM). The results evidenced the formation of highly ordered mesostructure, in which Ru particles were imbedded. The new carbon materials were further evaluated in the selective hydrogenation of cinnamaldehyde (CMA). By comparison with the traditional Ru/AC catalyst, our Ru-OMC samples exhibited much higher activity (2–14-fold) and up to 60% of selectivity to cinnamyl alcohol (CMO).
