Abstract

Small-sized (d_m = 2.07 nm) diamine (L)-stabilized ruthenium nanoparticles (NPs) were successfully synthesized upon the reaction of Ru(acetylacetonate)₃ with hydrogen in the presence of L and dichloromethane. The obtained L-capped ruthenium nanoparticles (Ru^L) were used as-synthesized and after deposition on the surface of carbon (C^K), featured by a high surface area (Ru^L@C^K, Ru content of 0.44 wt %) to selectively catalyze the hydrogenation of pyruvic acid in water at reaction temperatures up to 80 °C. The high efficiency of the latter catalyst emerged from parallel catalytic reactions conducted with the reference catalyst Ru@C^K, which was obtained by applying the same synthesis protocol in the absence of L. The role of L in the catalytic pyruvic acid hydrogenation reactions emerged from catalytic reactions combined with high-resolution transmission electron microscopic, X-ray photoelectron spectroscopic, and electrochemical studies.

二胺包覆钌纳米粒子在水中丙酮酸加氢的研究。

以Ru（乙酰丙酮酸）3为原料，在L和二氯甲烷存在下与氢反应，成功合成了小尺寸（dm = 2.07 nm）二胺稳定钌纳米颗粒（NPs）。制备的l包覆钌纳米颗粒（RuL）经沉积在碳（CK）表面，具有高表面积（RuL@CK， Ru含量0.44 wt %），可在80℃的反应温度下选择性催化丙酮酸加氢反应。后一种催化剂的高效率源于与参考催化剂Ru@CK的平行催化反应，参考催化剂Ru@CK是在没有L的情况下，采用相同的合成方案得到的。L在催化丙酮加氢反应中的作用是通过高分辨率透射电子显微镜、x射线光电子能谱和电化学研究相结合的催化反应得到的。
