Characteristic and electrocatalytic behavior of ruthenium Prussian blue analogue film in strongly acidic media

The remarkable stability of ruthenium Prussian blue analogue (designated as RuOx-PB) in strongly acidic media and for the enzymeless electrocatalytic oxidation of glucose was demonstrated in this study. The RuOx-PB combinative film neither dissolves nor denatures in concentrated acids, such as HClO4, HCl, H2SO4, and HNO3, investigated in this study. The catalytic response was found to directly proportional to [H+]. Such features are unique since neither RuOx- nor PB-based compounds are effective for direct carbohydrate oxidation in acidic media. The RuOx-PB film showed a highly reversible redox peak at ?1.2 V in 5 M HClO4 as a result of the fast proton-coupled electron transfer behavior of high valent ruthenium intermediate, RuVII/VI. The formation of internal multiple-hydrogen bond as well as the generation of the ?RuVII{double bond, long}O species in strongly acidic media were proposed to play a key role in this feature. The RuOx-PB holds high potential for use in catalytic oxidation, corrosion protection, biofuel cell, etc.

Tuning of redox potentials by introducing a cyclometalated bond to bis-tridentate ruthenium(II) complexes bearing bis(N -methylbenzimidazolyl) benzene or -pyridine ligands

A series of asymmetrical bis-tridentate cyclometalated complexes including [Ru(Mebib)(Mebip)]+, [Ru(Mebip)(dpb)]+, [Ru(Mebip)(Medpb)]+, and [Ru(Mebib)(tpy)]+ and two bis-tridentate noncyclometalated complexes [Ru(Mebip)2]2+ and [Ru(Mebip)(tpy)]2+ were prepared and characterized, where Mebib is bis(N-methylbenzimidazolyl)benzene, Mebip is bis(N-methylbenzimidazolyl) pyridine, dpb is 1,3-di-2-pyridylbenzene, Medpb is 4,6-dimethyl-1,3-di-2- pyridylbenzene, and tpy is 2,2?:6?,2?-terpyridine. The solid-state structure of [Ru(Mebip)(Medpb)]+ is studied by X-ray crystallographic analysis. The electrochemical and spectroscopic properties of these ruthenium complexes were studied and compared with those of known complexes [Ru(tpy)(dpb)]+ and [Ru(tpy)2]2+. The change of the supporting ligands and coordination environment allows progressive modulation of the metal-associated redox potentials (Ru II/III) from +0.26 to +1.32 V vs Ag/AgCl. The introduction of a ruthenium cyclometalated bond in these complexes results in a significant negative potential shift. The RuII/III potentials of these complexes were analyzed on the basis of Lever’s electrochemical parameters (E L). Density functional theory (DFT) and time-dependent DFT calculations were carried out to elucidate the electronic structures and spectroscopic spectra of complexes with Mebib or Mebip ligands.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 10049-08-8 is helpful to your research., category: ruthenium-catalysts
