Electrocatalysis is a special field in Electrochemistry that hasgained a special growth after the late eighties due to theapplication of new hybrid techniques. However, most of theapplications have run for academic purposes ...

We have investigated the stability and catalytic activity of epitaxial overlayers of rhodium on Au(111) and Pd(111). Both surfaces show a strong affinity for hydrogen. We have calculated the energy of adsorption both for ...

A gas-diffusion gold-ring microelectrode used as scanning electrochemical microscopy tip was fabricated. Compared to the ring-tip for droplet dispensation reported before, the as sa-fabricated micropipette tip has a larger ...

The reduction of molecular oxygen in triplet and singlet spin states at metal electrodes is analyzed in the framework of quantum mechanical theory of charge transfer. Both outer- and inner-sphere mechanism is considered. ...

This work reports an electrode material containing molybdenum phosphate that shows a very interesting behavior as an electrocatalyst for the reduction of oxygen to water (ORR) in acid medium. The material is electrodeposited ...

Here we demonstrate that every time Au and Ag NPs are physically mixed together they outperform their monometallic counterparts upon electrocatalysis of hydroquinone (HQ) and electrophoretic deposition (EPD) coverage.We ...

Geobacter sulfurreducens cells have the ability to exchange electrons with conductive materials, and the periplasmic cytochrome PccH plays an essential role in the direct electrode-to-cell electron transfer in this bacterium. ...

The coordination of PySSPy to FePc was monitored by UV/Vis spectroscopy while the adsobed FePc, anchored by PyS−Au(111), was examined by in situ STM in 0.1 M HClO4 and X-ray photoelectron spectroscopy (XPS). Rotating-dis ...

In the present contribution we have focused on the electrochemical adsorption of a proton from the solution - the Volmer reaction - on a variety of systems based on bimetallic nanostructures - clusters and wires - of Pd ...

We show how a theory for electrocatalysis developed in our group can be combined with density-functional theory in order to obtain free-energy surfaces for electrochemical reactions. The combined theory is applied to the ...
