Impact of Plasmonic Photothermal Effects on the Reactivity of Au Nanoparticle Modified Graphene Electrodes Visualized Using Scanning Electrochemical Microscopy

Atomically thin graphene electrodes enable the modulation of interfacial reactivity by means of underlying substrate effects. Here we show that plasmonic excitation of microscopic arrays composed of 50 nm Au nanoparticles situated underneath a graphene interface results in localized enhancements on the electrochemical readout. We used scanning electrochemical microscopy (SECM) in the feedback and H2O2 collection modes to identify the role of the generated plasmons on the electrochemical response. Using electrochemical imaging, supported by finite-element method simulations, we confirmed that a temperature rise of up to ?30 K was responsible for current enhancements observed for mass transfer- limited reactions. On single-layer graphene (SLG) we observed a shift in the onset of H2O2 generation which we traced back to photothermal induced kinetic changes, raising ko? from 1.1 ¡Á 10-8 m/s to 2.2 ¡Á 10-7 m/s. Thicker 10-layer graphene electrodes displayed only a small kinetic difference with respect to SLG, suggesting that photothermal processes, in contrast to hot carriers, are the main contributor to the observed changes in interfacial reactivity upon illumination. SECM is demonstrated to be a powerful technique for elucidating thermal contributions to reactive enhancements, and presents a convenient platform for studying sublayer and temperature-dependent phenomena over individual sites on electrodes.

The hydrogen-bonded ferrocenylmethanol: Mediation of electron transfer for physically adsorbed glucose oxidase

The mechanism of electron transfer of ferrocenylmethanol through the self-assembled monolayer (SAM) of mercaptosuccinic acid (MSA) on gold was investigated. A key finding is that the hydrogen-bonded FcMeOH plays the role of a mediator in the electron transfer involving the physically adsorbed glucose oxidase at the MSA SAM surface. The space-conformation of the hydrogen-bonding between FcMeOH and MSA was obtained by computational methods. The FcMeOH interacts with MSA via the strong hydrogen bond with the short distance around 1.9 A at two different binding sites, approving the statements of hydrogen-bonding. The intermolecular hydrogen-bonding between redox mediator (FcMeOH) and the artificial self-assembled monolayer (MSA) is evident, and the mechanistic study of heterogeneous electron transfer kinetics is meaningful for the biosensor applications.

Epoxy-encapsulated ceramic superconductor microelectrodes

A procedure is outlined for fabricating well-behaved microelectrodes from ceramic pellets of YBa2Cu3O7 and Bi2Sr2CaCu2O8 which involves systematic polishing of an epoxy-encapsulated superconductor chip, under Et4NClO4/acetonitrile solution, to a potentiometric end point. Voltammetry of the resulting microelectrodes in acetonitrile is illustrated and compared to that arising from alternative superconductor electrode geometries. The microelectrodes have active electrode surface areas ranging from 2 ¡Á 10-6 to 3 ¡Á 10-4 cm2, as characterized electrochemically and microscopically. The results are significant steps toward developing the methodology necessary to study the electrochemical response of high temperature superconductor phases at temperatures below their superconductor critical temperature.

The synthesis and properties of ferroceno[1?,2?;1?,2?]bis(1,3-dithiol-2-thione and -2-one) derivatives

The t-butyl and bis(t-butyl) derivatives of hexathia[3.3]ferrocenophane were prepared from the corresponding trithia[3]ferrocenophanes. The former was a mixture of chair-chair and chair-boat isomers, and the latter existed only chair-boat isomer. The hexathia[3.3]ferrocenophanes were led to the tetrathiols with LiAlH4, which allowed to react with 1,1?-thiocarbonyldiimidazol to give the corresponding ferroceno[1?,2?;1?,2?]bis(1,3-dithiol-2-thione) derivatives. Mono t-butyl and unsubstituted analogs were prepared in a similar manner. The X-ray structural determination showed that these derivatives adopted the conformation in which the 1,3-dithiol-2-thione rings were heaped on top of each other. In the crystal of ferroceno[1?,2?;1?,2?]bis(1,3-dithiol-2-thione), the molecules packed so as to put the axis of molecule in order and to overlap one another above and below. The desulfurizative coupling of the ferroceno[1?,2?;1?,2?]bis(1,3-dithiol-2-thione) derivatives was unsuccessful.

Fabrication, characterization and application of graphite ring ultramicroelectrodes for kinetic studies of fuel cell reactions under high mass-transport rates

This work describes the preparation of nanocrystalline-graphite inlaid ring ultramicroelectrodes (UMEs) with inner diameters larger than 0.3 mum and thicknesses as low as a few nanometers. The geometric parameters of these UMEs were determined by a combination of optical microscopy and cyclic voltammetry data. These UMEs permit to establish mass-transport rates as large as those obtained on nanometer-sized hemispherical UMEs. They have very low electrochemical activity in acid and can function very well as catalyst supports for kinetic studies of fuel cell reactions such as the hydrogen oxidation reaction (hor). In order to demonstrate the outstanding utility of these electrodes, compact Pt films were electrodeposited on graphite ring UMEs and used to carry out a kinetic study of the hor in acid medium.

Homogeneous Hydrogenation with a Cobalt/Tetraphosphine Catalyst: A Superior Hydride Donor for Polar Double Bonds and N-Heteroarenes

The development of catalysts based on earth abundant metals in place of noble metals is becoming a central topic of catalysis. We herein report a cobalt/tetraphosphine complex-catalyzed homogeneous hydrogenation of polar unsaturated compounds using an air- and moisture-stable and scalable precatalyst. By activation with potassium hydroxide, this cobalt system shows both high efficiency (up to 24 000 TON and 12 000 h-1 TOF) and excellent chemoselectivities with various aldehydes, ketones, imines, and even N-heteroarenes. The preference for 1,2-reduction over 1,4-reduction makes this method an efficient way to prepare allylic alcohols and amines. Meanwhile, efficient hydrogenation of the challenging N-heteroarenes is also furnished with excellent functional group tolerance. Mechanistic studies and control experiments demonstrated that a CoIH complex functions as a strong hydride donor in the catalytic cycle. Each cobalt intermediate on the catalytic cycle was characterized, and a plausible outer-sphere mechanism was proposed. Noteworthy, external inorganic base plays multiple roles in this reaction and functions in almost every step of the catalytic cycle.

Investigation of processing effects on the corrosion resistance of Ti20Mo alloy in saline solutions

The electrochemical properties of Ti20Mo alloys prepared using different fabrication procedures, namely cold crucible levitation melting (CCLM) and powder sintering, were investigated using linear potentiodynamic polarization and EIS measurements. The surface condition was established using AFM, with the observation of a more porous surface finish in the case of powder sintering. A major effect of surface conditioning on the corrosion resistance of Ti20Mo alloys was observed, where the compact finish exhibits a superior corrosion resistance in chloride-containing saline solutions. Less insulating surfaces towards electron exchange resulted for the more porous finish as revealed by scanning electrochemical microscopy (SECM).
