We report an application of the scanning electrochemical microscope that exploits its ability to spatially map the kinetics of heterogeneous electron-transfer reactions in order to perform screening measurements for combinatorial studies of electrooxidation catalysts. The ability to measure the activity of catalyst surfaces toward the hydrogen oxidation reaction via tip-sample feedback is used to characterize the activity of PtxRuy and PtxRuyMoz catalysts as a function of composition and electrode potential. Multielement band electrodes containing various compositions of PtxRuy, and PtxRuyMoz deposits are created via pulsed electrochemical deposition onto patterned substrates. Catalyst compositions are verified through a combination of Auger electron spectroscopy and energy-dispersive X-ray spectroscopy. Activity toward the hydrogen oxidation reaction is probed in sulfuric acid solutions by using a scanning microelectrode tip placed in close proximity to the catalyst surfaces. The tip potential is held at a value where protons are reduced to hydrogen at a diffusion-limited rate. Tip-produced hydrogen is converted back to protons via oxidation at the catalyst surfaces. This leads to an increase in feedback current at the tip, whose magnitude directly reflects the substrate’s rate constant for hydrogen oxidation. Monitoring the feedback response while scanning the microelectrode tip over catalyst samples of various compositions is used to deduce the onset of activity. The onset of hydrogen oxidation on these PtxRuy, and PtxRuyMoz samples in the presence of an adsorbed monolayer of carbon monoxide is determined by performing screening studies as a function of electrode potential. The compositions with the lowest onset potentials are identified, and the results are compared with carbon monoxide stripping experiments.

A unique ruthenium(II) complex, tris(4-methyl-2,2?-bipyridyl- 4?-carboxaldehyde)Ru(II) hexafluorophosphate [Ru(CHO-bpy) 3](PF6)2, has been designed and synthesized as a highly sensitive and selective luminescence probe for the recognition and detection of cysteine (Cys) and homocysteine (Hcy). The almost non-luminescent probe can rapidly react with Cys and Hcy to yield the corresponding thiazolidine and thiazinane derivatives, accompanied by the remarkable luminescence enhancement and a large blue-shift of the maximum emission wavelength from 720 to 635 nm. The dose-dependent luminescence enhancement of the probe shows a good linearity in the Cys/Hcy concentration range of 15 to 180 muM with the detection limits of 1.41 muM and 1.19 muM for Cys and Hcy, respectively. Furthermore, the luminescence response of the probe is highly specific to Cys/Hcy only even in the presence of various amino acids, protein, and DNA. The results of this work not only demonstrate the efficacy and advantages of the Ru(II) complex-based luminescence probe for the sensitive and selective detection of Cys/Hcy but also provide a useful strategy for the rational design of Ru(II) complex-based luminescence probes for various biological molecules.

A well-crystallized mesoporous hydrous ruthenium dioxide (RuO xHy) with high surface area of 120 m2 g -1 and high electrochemical catalytic activity has been synthesized by a replicating route with the mesoporous silica (KIT-6) as hard template. The materials were characterized by means of thermo-gravimetric analysis (TG), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and N2 sorption. The electrocatalytic activity of the samples for methanol oxidation were investigated by cyclic voltammetry (CV) and linear scan voltammetry (LSV) techniques. A mixed gas of CO and O2 was adopted to investigate the effect of gas treatment on the electrochemical activity of the samples. The results show that the electrocatalytic activity of the prepared mesoporous RuOxHy and 3 wt% Pt/mesoporous RuOxH y toward methanol oxidation was much enhanced after treatment with a mixed gas of CO and O2. The enhanced electrochemical catalytic activity of the materials might be attributed to the structure activation during the gas treatment and the high surface area of RuOxHy matrix with mesoporous structure.

Complexes [ML3]2+ of the bidentate ligand 2-(1H-imidazol-2-yl)pyridine were prepared with iron(II), cobalt(II), and ruthenium(II). The electronic spectra suggest the ligand to be a weaker sigma-donor and pi-acceptor than the closely related 2,2?-bipyridine. The complexes are readily deprotonated by addition of base, and the effect of the deprotonation is to lower the MIII/MII redox potential by roughly 900 mV. This is roughly 75% of the drop observed for related complexes of 2,6-di-1H-imidazol-2-ylpyridine, and suggests the effect to be largely coulombic in origin.

Three compounds of general formula (NBu4)(MIIRuIII(ox)3] have been synthesized; NBu4+ stands for tetra-n-butylarnmonium, M for Mn, Fe, and Cu, and ox2- for the oxalate dianion. The X-ray powder patterns for the three derivatives have revealed that these compounds are isostructural with (NBu4)[MnIICrIII(ox)3], whose crystal structure was known, and the cell parameters have been refined in the R3c space group. The (NBu4)[MIIRuIII(ox)3] compounds are new examples of two-dimensional bimetallic assemblies with oxalate bridges. The temperature (T) dependences of the magnetic susceptibility (chiM) in both the dc and ac modes and the field dependences of the magnetization have been investigated. The local spins are SRu = SCu 1/2, SMn = 5/2, and SFe = 2. The RuIII-MII interaction has been found to be antiferromagnetic for M = Fe and Cu and ferromagnetic for M = Mn. The two compounds (NBu4)[FeIIRuIII(ox)3] and (NBu4)[CuIIRuIII(ox)3] exhibit a ferrimagnetic behavior, characterized by a minimum in the chiMT versus T plots. (NBu4)[FeIIRuIII(ox)3] exhibits a long-range magnetic ordering at Tc = 13 ± 1 K. A slight frequency dependence of the out-of-phase ac magnetic response has been observed. The field dependence of the magnetization in the magnetically ordered state has revealed a rather strong coercivity, with a coercive field of 1.55 kOe at 2 K. A theoretical model has been used to determine the magnitude of the RuIII-MII interactions, with M = Mn and Fe. This model is based on a quantum-classical spin approach together with Monte Carlo simulations. The interaction parameters have been found as J = 1.04 cm-1 for (NBu4)[MnIIRuIII)(ox)3] and -9.7 cm-1 for (NBu4)[FeIIRuIII(ox)3], with a spin Hamiltonian of the type -JSigmai,jSRu,i·SM,j. The magnetic properties of these compounds have been discussed. In particular, it has been emphasized that the symmetry rules governing the nature and the magnitude of the interaction between two 3d magnetic metal ions seem not Co be valid anymore for 4d ions such as RuIII.

The EPR spectra of CsMgCl3 crystals doped with Gd(III) and Ru(III) contain the resonances from a magnetically coupled Gd(III)-Ru(III) pair.The pair spectrum exhibits the fine structure characteristic of a Gd(III) ion (S=7/2) in an axial lattice site.At 77 K the weak coupling with the Ru(III) ion (S=1/2) splits each resonance into a doublet.The spectrum is well enough resolved to allow a characterization as a function of crystal orientation.A spin Hamiltonian which assumes a simple anisotropic interaction between the two ions is adequate to describe the spectrum (Etap=JzSzSz’+Jxy(SySx’+SySy’); where =+0.0055 cm-1 and =0.020 cm-1).The analysis determines that the principal g values of Gd(III) and Ru(III) have opposite sign (for Gd(III): gz=+1.991 and =1.991; for Ru(III): gz’=-2.35 and =1.62).The magnetic properties of the Gd(III)-Ru(III) dimer are discussed.As a part of this analysis, the spectra of a number of monomeric centers containing Gd(III) and Ru(III) were characterized.The properties of these centers are also discussed.
