In the present worldwide situation, the transition to a more sustainable hydrogen economy from the prevailing energy infrastructure is gaining great attention. Herein, for hydrogen production from biomass-derived sorbitol, we employed a bifunctional NNN–Ru system bearing protic arms in a ligand scaffold liable for a metal–ligand cooperativity pathway as well as a secondary-coordination-sphere hydrogen-bonding
在当前的全球形势下,从盛行的能源基础设施向更可持续的氢经济的转变正受到广泛关注。在此,对于从生物质衍生的山梨糖醇生产氢气,我们采用了双功能 NNN-Ru 系统,在配体支架中带有质子臂,负责金属-配体协同途径以及二级配位球氢键相互作用,以实现适当的活性中心的底物取向。在山梨糖醇重整制氢过程中实现了最大周转数 35359。发现该催化剂在多达七次运行中保持活性,具有高效的催化活性。进行了一系列核磁共振研究,揭示了功能化配体在催化过程中的积极参与。
