Automated systems for electrochemical synthesis and high throughput screening of catalytic materials were developed and used to prepare a library of nanoparticulate gold supported on TiO2. A two-dimensional array (library) of Au was synthesized by pulsed cathodic electrodeposition onto a thermally oxidized titanium dioxide substrate. Variations in particle size across the library were created b...

The fabrication of nanostructured bimetallic materials through electrochemical routes offers the ability to control the composition and shape of the final material that can then be effectively applied as (electro)-catalysts. In this work a clean and transitory hydrogen bubble templating method is employed to generate porous Cu-Au materials with a highly anisotropic nanostructured interior. Sign...

The mechanism of energy conversion in a direct glycerol fuel cell (DGFC) is governed by the anode supported heterogeneous steps of glycerol electro-oxidation. In aerated alkaline electrolytes, glycerol also participates in a base catalyzed process, which can release certain species mixing with the anode catalyzed surface products. As a result, selective probing of the surface catalytic reaction...

In the present work, a nanocomposite of two-dimensional WSe2 nanosheets with poly(3,4‑ethylenedioxythiophene (WSe2@PEDOT) was prepared by facile hydrothermal method and characterized in terms structural morphological analyses. This nano­composite used to modify glassy carbon electrode for construction an electrochemical sensing platform simultaneous determination dopamine (DA) uric acid (UA) pr...

The trends in electronic structure of Bi 3+ and 2+ as luminescent dopant wide bandgap inorganic compounds that pure Bi-compounds for photocatalytic splitting water are explored by determination vacuum referred electron binding energies. Spectroscopic data combined with the chemical shift model from luminescence field on flatband potentials electrochemistry provide most needed data. Occasionally...

Self-propelling particles or microswimmers have opened a new field of investigation with both fundamental and practical perspectives. They represent very convenient model objects for experimental studies active matter, implications in nano-robotics, drug delivery, more. Here, we summarize recent advances theoretical description the self-propulsion catalytic that non-uniformly release ions, incl...

objective: in this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. methods: the base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. lorentz electric force, which is used as stimulating flow factor, is created by appl...

the performance of a plug flow electrocoagulation reactor for the treatment of cattle abattoir(slaughterhouse) wastewater was investigated. a cylindrical iron reactor was operated as a cathode at arecycling batch mode while three iron rods located at the center of the reactor were used as an anode. theeffects of different parameters, including the current density, the supporting electrolyte dos...

Today development of efficient catalytic systems for selective oxidation alcohols to aldehydes remains not only a major concern in basic chemistry research but also significant challenge the chemical industry. One promising green and sustainable approach increase selectivity as well waste reduction minimize use toxic and/or hazardous substances is electro-catalytic acceptorless dehydrogenation ...
