For Ru and Ir oxide electrodes sintered at different temperatures, in this work, surface resistivity, X-ray photoelectron spectroscopy, electrode lifetime, voltammetric charge capacity, and total organic carbon of 4-chlorophenol (4CP) decomposition at the electrodes were measured, and then intermediates during the electrolysis were identified by gas chromatography-mass spectroscopy to predict the destruction path of 4CP at the electrodes. A sintering temperature of around 650C, rather than 400-550C suggested in the literature for the fabrication of Ru and Ir oxide electrode, showed the highest organic destruction yield. The sintering temperature strongly affected the electrode lifetime as well. During the high temperature sintering, increase of the sintering time caused the oxidation of the Ti substrate to result in the increase of oxide weight of the electrode and the solid diffusion of the generated TiO2 to the electrode surface, which decreased the electrode activity so that the organic destruction yield went down slowly. The destruction path of 4CP at a high temperature-sintered electrode was suggested to be different from that at a low temperature-sintered one. The Ru oxide electrode sintered at 450C generated several complicated aliphatic intermediates.

By adjusting the pH of the reaction medium, the stoichiometry, the reactant concentrations, and heating time and temperature, reactive mono-and binuclear Ru(III) and Rh(III) chloro aqua complexes and various hydrazone tautomers were obtained. This provided for the synthesis of new complexes promising as cardiotonic agents and analytical forms for determination of metal traces in solutions. Correlation analysis was applied to describe the type of M-L chemical bonding. The ruthenium formal oxidation state and local environment in the coordination polyhedra of the synthesized complexes were determined by X-ray photoelectron spectroscopy.

Rationally designed RuO2-based Deacon catalysts can contribute to massive energy saving compared to the current electrolysis process in chemically recycling HCl to produce molecular chlorine. Here, we report on our integrated approach between state-of-the-art experiments and calculations. The aim is to understand industrial Deacon catalyst in its realistic surface state and to derive mechanistic insights into this sustainable reaction. We show that the practically relevant RuO2/SnO2 consists of two major RuO2 morphologies, namely 2-4 nm-sized particles and 1-3-ML-thick epitaxial RuO2 films attached to the SnO2 support particles. A large fraction of the small nanoparticles expose {1 1 0} and {1 0 1} facets, whereas the film grows with the same orientations, due to the preferential surface orientation of the rutile-type support. Steady-state Deacon kinetics indicate a medium-to-strong positive effect of the partial pressures of reactants and deep inhibition by both water and chlorine products. Temporal Analysis of Products and in situ Prompt Gamma Activation Analysis strongly suggest a Langmuir-Hinshelwood mechanism and that adsorbed Cl poisons the surface. Under relevant operation conditions, the reactivity is proportional to the coverage of a specific atomic oxygen species. On the extensively chlorinated surface that can be described as surface oxy-chloride, oxygen activation is the rate-determining step. DFT-based micro-kinetic modeling reproduced all experimental observations and additionally suggested that the reaction is structure sensitive. Out of the investigated models, the 2 ML RuO2 film-covered SnO2 gives rise to significantly higher reactivity than the (1 0 1) surface, whereas the 1 ML film seems to be inactive.

Selective oxo-functionalisation of C-H bond with t-BuOOH catalysed by [RuIII(amp)(bipy)Cl] complex (H2amp=N-(hydroxyphenyl)salicyldimine; Bipy=2,2?bipyridyl)

[RuIII(amp)(bipy)Cl] complex (1) has been synthesised and characterised by physico-chemical methods. Complex-1 is found to be an effective catalyst in the oxidation of cyclohexene to cyclohexene-1-ol, cyclohexane to cyclohexanol and cyclohexanone, stilbenes to stilbene epoxides and benzaldehyde upon reaction with tert-butylhydroperoxide (t-BuOOH). A high valent Ru(V)-oxo species formed as a catalytic intermediate in the reaction of complex-1 with t-BuOOH is proposed as the source of oxygen in the oxidised product. Kinetic data suggests that the formation Ru(V)-oxo is substitution controlled. The results of the product distribution in the present investigation clearly indicate the high electrophilic nature of Ru=O bond in [RuV(amp)(bipy)O]+ intermediate complex which leads to high affinity for atomic hydrogen/hydride abstraction.

Direct regeneration of NADH on a ruthenium modified glassy carbon electrode

The regeneration of NADH in a batch electrochemical reactor using a ruthenium modified glassy carbon electrode (RuGC) has been investigated. The information on the structure of the electrode/electrolyte interface in the presence of NAD+ in the solution, the kinetics of NAD+ reduction, and the batch-electrolysis NADH regeneration has been obtained using electrochemical techniques of dc linear potential (LP) and constant potential (CA) polarization, ac differential capacitance (DC), and electrochemical impedance spectroscopy (EIS). It has been shown that the modification of GC by a sub-monolayer of Ru can provide an electrode surface capable of reducing NAD+ directly to NADH at a high yield of enzymatically active 1,4-NADH (96%). From the electrochemical point of view, the reaction is irreversible and occurs at high cathodic overpotentials, where the reaction rate is controlled by the surface diffusion of electroactive species. EIS measurements have shown that the electrode/electrolyte interface and the corresponding charge- and mass-transfer processes can be described by an electrical equivalent circuit composed of two time constants in parallel, with the additional contribution of a mass-transport Warburg impedance element. The time constant recorded at higher frequencies represents the response of a GC part of the electrode surface, while the lower-frequency time constant can be related to the response of Ru sites on the electrode surface. It has been determined that the NAD+ reduction reaction is of first order with respect to NAD+. The calculated apparent heterogeneous reaction rate constant values are rather low, which is due to the slow mass-transport of electroactive species at the electrode surface. The kinetic analysis has demonstrated that a very good agreement between the apparent heterogeneous reaction rate constant values calculated using three different experimental techniques is obtained.
