Efficient photochemical water oxidation by a dinuclear molecular ruthenium complex.
Herein is described the preparation of a dinuclear molecular Ru catalyst for H2O oxidation. The prepared catalyst mediates the photochemical oxidation of H2O with an efficiency comparable to state-of-the-art catalysts.
متن کاملMechanism of Water Oxidation Catalyzed by a Dinuclear Ruthenium Complex Bridged by Anthraquinone
We synthesized 1,8-bis(2,2′:6′,2”-terpyrid-4′-yl)anthraquinone (btpyaq) as a new dimerizing ligand and determined its single crystal structure by X-ray analysis. The dinuclear Ruthenium complex [Ru2(μ-Cl)(bpy)2(btpyaq)](BF4)3 ([3](BF4)3, bpy = 2,2′-bipyridine) was used as a catalyst for water oxidation to oxygen with (NH4)2[Ce(NO3)6] as the oxidant (turnover numbers = 248). The initial reaction...
متن کاملDinuclear manganese complexes for water oxidation: evaluation of electronic effects and catalytic activity.
During recent years significant progress has been made towards the realization of a sustainable and carbon-neutral energy economy. One promising approach is photochemical splitting of H2O into O2 and solar fuels, such as H2. However, the bottleneck in such artificial photosynthetic schemes is the H2O oxidation half reaction where more efficient catalysts are required that lower the kinetic barr...
متن کاملStable iridium dinuclear heterogeneous catalysts supported on metal-oxide substrate for solar water oxidation.
Atomically dispersed catalysts refer to substrate-supported heterogeneous catalysts featuring one or a few active metal atoms that are separated from one another. They represent an important class of materials ranging from single-atom catalysts (SACs) and nanoparticles (NPs). While SACs and NPs have been extensively reported, catalysts featuring a few atoms with well-defined structures are poor...
متن کاملWater oxidation catalyzed by a dinuclear Mn complex: a functional model for the oxygen-evolving center of photosystem II.
A dimanganese(II) bis-aquo complex [Mn2(cmep)2(H2O)2](ClO4)2, (cmep = N-carboxymethylN’-methyl-N,N’-bis(2-pyridylmethyl)-1,2-ethandiamine), catalyzes the oxidation of water by butylhydrogenperoxide (TBHP) to dioxygen with many turnovers and without degradation. O isotope labelling shows the reaction is highly specific: One oxygen atom in the product dioxygen is derived from water, the other is ...
