  Catalytic Water Oxidation by Mononuclear Ru Complexes with an Anionic Ancillary Ligand

  摘要：

  Mononuclear Ru-based water oxidation catalysts containing anionic ancillary ligands have shown promising catalytic efficiency and intriguing properties. However, their insolubility in water restricts a detailed mechanism investigation. In order to overcome this disadvantage, complexes [Ru-II(bpc)(bpy)OH2](+) (1(+), bpc = 2,2'-bipyridine-6-carboxylate, bpy = 2,2'-bipyridine) and [Ru-II(bpc)(pic)(3)](+) (2(+), pic = 4-picoline) were prepared and fully characterized, which features an anionic tridentate ligand and has enough solubility for spectroscopic study in water. Using Ce-IV as an electron acceptor, both complexes are able to catalyze O-2-evolving reaction with an impressive rate constant. On the basis of the electrochemical and kinetic studies, a water nucleophilic attack pathway was proposed as the dominant catalytic cycle of the catalytic water oxidation by 1(+), within which several intermediates were detected by MS. Meanwhile, an auxiliary pathway that is related to the concentration of Ce-IV was also revealed. The effect of anionic ligand regarding catalytic water oxidation was discussed explicitly in comparison with previously reported mononuclear Ru catalysts carrying neutral tridentate ligands, for example, 2,2':6',2 ''-terpyridine (tpy). When 2(+) was oxidized to the trivalent state, one of its picoline ligands dissociated from the Ru center. The rate constant of picoline dissociation was evaluated from time-resolved UV-vis spectra.

  Two series of ruthenium polypyridyl complexes (8 examples) have been prepared and assessed for electrocatalytic CO2 reduction reaction. For the most active complex, a TONmax of more than 1000 per second was achieved for the catalytic CO2 reduction with CO as the major product.

  已经制备了两个系列的钌多吡啶基配合物（8 个示例）并评估了其用于电催化 CO 2还原反应。对于最活跃的复合物，以 CO 为主要产物的催化CO 2还原达到每秒超​​过 1000 吨的最大值。
